The Phone Ending is the ultimate goal of Drain the Lake. Your phone fell into the lake, and you must drain the water bucket by bucket to reach the bottom where it rests. This guide provides a strategy overview focused on optimal upgrade paths, bucket selection, and quick checkpoint progression. For a detailed step-by-step walkthrough with exact upgrade level requirements for each zone, see our Complete Walkthrough.
Overview — Six Checkpoints to Your Phone
| Checkpoint | Depth | Skill Tree Requirement | Badge |
|---|---|---|---|
| Shipwreck | Shallow | Basic Depth Unlock | Deep Dive |
| Cavern | Mid | Moderate Depth Unlock | — |
| Mineshaft | Moderate | Significant Depth Unlock | The Mines |
| Molten | Deep | Heavy Depth Unlock | Fire Below |
| Lost City | Very Deep | Major Depth Unlock | Ancient Ruins |
| Abyss | Maximum | Maximum Depth Unlock | Find My Phone, Into the Abyss |
Depth Token Scaling
Understanding token multipliers at each depth is critical for efficient progression. Deeper water yields significantly more tokens per bucket, making depth investment the most impactful long-term strategy.
| Zone | Token Multiplier | Relative Value vs. Surface |
|---|---|---|
| Surface | 1x | Baseline |
| Shipwreck | 1.5-2x | 50-100% more tokens |
| Cavern | 2-3x | 100-200% more tokens |
| Mineshaft | 3-4x | 200-300% more tokens |
| Molten | 4-6x | 300-500% more tokens |
| Lost City | 6-8x | 500-700% more tokens |
| Abyss | 8-12x | 700-1100% more tokens |
The jump from Lost City to Abyss represents the largest single multiplier increase in the game. Players who reach the Abyss with a well-upgraded Token Multiplier skill can earn over 12x the surface rate, making endgame farming dramatically faster than early progression.
Checkpoint 1: Shipwreck
The Shipwreck is your first destination beneath the surface. This shallow-depth zone introduces you to the concept of higher-value water tiers.
What to expect:
- Sunken wreckage and debris
- Water that pays ~1.5-2x more tokens than the surface
- Minimal hazards — a safe introduction to depth exploration
- The Deep Dive badge for reaching a deep zone
Recommended upgrades before pushing:
- Fill Speed Lv 3+
- Bucket Capacity Lv 2+
- Plastic Bucket (200 Gems) or better
Strategy tips: The Shipwreck is where you establish your core active loop. Focus on Fill Speed above all else — faster fill times mean more trips per minute, which compounds with the 1.5-2x token bonus. Avoid spending tokens on Automation or Movement Speed at this stage; the spend-immediately principle applies here. Every token you invest in Fill Speed and Capacity accelerates your next upgrade cycle. The Plastic Bucket's +5% Fill Speed bonus is noticeable but not mandatory; the Common bucket suffices if you're saving Gems for a Metal Bucket later.
Checkpoint 2: Cavern
The Cavern is a mid-depth zone with new environmental features. The cave environment provides moderately higher water value.
What to expect:
- Underground cave formations
- Water value approximately 2-3x surface rate
- Moderate difficulty — manageable with mid-game upgrades
- New visual themes that make exploration interesting
Recommended upgrades:
- Fill Speed Lv 4-5+
- Bucket Capacity Lv 3+
- Token Multiplier Lv 1-2+
- Metal Bucket or better
Strategy tips: The Cavern is where Token Multiplier upgrades become worth investing in. With water valued at 2-3x surface rate, each Token Multiplier level has a larger absolute impact than at the surface. The Metal Bucket (500 Gems, Uncommon) provides improved drain efficiency, which reduces the time your bucket spends full before you reach the drain point. This efficiency gain is more valuable than its stats suggest because it tightens your active loop. If you haven't earned enough Gems from badges and chests, refer to our badges guide for easy completions like First Drop (10 Gems) and Plunge (10 Gems).
Checkpoint 3: Mineshaft
The Mineshaft introduces an industrial theme with mechanical elements. Water value increases significantly here.
What to expect:
- Industrial tunnels and machinery
- Water value approximately 3-4x surface rate
- The Mines badge upon arrival
- More challenging depth that requires a solid active loop
Recommended upgrades:
- Fill Speed Lv 5-6+
- Bucket Capacity Lv 4+
- Token Multiplier Lv 2-3+
Strategy tips: The Mineshaft marks the transition from early-mid to late-mid game. The 3-4x multiplier makes this a viable farming zone if you're not yet ready to push deeper. At this stage, your active loop should feel smooth — fill, move to drain, drain, return. If any part of this cycle feels slow, prioritize the corresponding Skill Tree family before attempting Molten. Movement Speed upgrades become more relevant here because the distance between fill zones and drain points increases with depth. The Magnet Bucket (1200 Gems, Rare) is a strong consideration for this zone, as its item attraction ability helps collect chests and gems while draining.
Checkpoint 4: Molten
The Molten zone is lava-themed and represents a significant difficulty spike. The danger is visual — lava and fire effects — but the water tiers are extremely lucrative.
What to expect:
- Lava-themed environment with dramatic visuals
- Water value approximately 4-6x surface rate
- The Fire Below badge upon arrival
- Requires well-optimized active loop
Recommended upgrades:
- Fill Speed Lv 7+
- Bucket Capacity Lv 5+
- Token Multiplier Lv 3-4+
- Magnet Bucket or Toxic Bucket recommended
Strategy tips: The Molten zone is where bucket choice matters significantly. The Toxic Bucket's +10% Token earnings and 10% chance of instant drain when full can dramatically accelerate your loop — the instant drain proc effectively gives you free tokens without the travel time. If you're using the Magnet Bucket from the Mineshaft, consider switching to Toxic for the raw token boost. The 4-6x multiplier makes this zone one of the best mid-game farming spots; many players choose to farm here extensively before pushing to Lost City. The Fire Below badge provides a Gem reward upon first arrival.
Checkpoint 5: Lost City
The Lost City is an ancient ruins zone near the bottom. High-value water makes this one of the most profitable areas.
What to expect:
- Ancient architecture and mysterious artifacts
- Water value approximately 6-8x surface rate
- The Ancient Ruins badge upon arrival
- One of the best farming zones if your loop is strong
Recommended upgrades:
- Fill Speed Lv 8+
- Bucket Capacity Lv 6+
- Token Multiplier Lv 4-5+
- Golden Bucket or Ancient Bucket recommended
Strategy tips: The Lost City's 6-8x multiplier is a massive jump from Molten. Players with the Golden Bucket (2000 Diamonds, Legendary) will see the best returns here due to its Token earnings increase and superior gem farming capability. The Ancient Bucket (Legendary, +10% Token, higher-tier gem digs) is equally strong if you've unlocked it through 10 badges and the IWTM10GTMPLS group join. If you lack either Legendary bucket, the Toxic Bucket remains a solid choice for its passive token boost. This zone is the last viable farming stop before the Abyss — ensure your Skill Tree is well-optimized before the final push.
Checkpoint 6: Abyss — Phone Ending
The Abyss is the final checkpoint. Here you will find your phone and complete the game.
What to expect:
- Deep, dark water at maximum depth
- Water value approximately 8-12x surface rate
- The Find My Phone badge (pick up your phone)
- The Into the Abyss badge (reaching the Abyss)
- 62% of players have reached this point
To complete the Phone ending:
- Reach the Abyss checkpoint with Maximum Depth Unlock
- Navigate through the dark environment to the phone location
- Pick up your phone
- The game congratulates you — but does not end
- You can continue draining, upgrading, and collecting badges
Strategy tips: The Abyss is visually the darkest zone, making navigation more challenging than previous checkpoints. The 8-12x token multiplier makes this the most efficient farming zone in the game, but only if your loop is fast enough to handle the depth. Maximum Depth Unlock is required, which represents a significant token investment in the Skill Tree. Don't rush to the Abyss with underdeveloped Fill Speed or Capacity — a slow loop at 8-12x multiplier can still underperform a fast loop at 6-8x in Lost City. Once you pick up your phone, the Find My Phone badge awards a substantial Gem reward.
Bucket Selection for the Phone Ending Run
Choosing the right bucket can save hours of progression time. Below is a comparison of buckets relevant to a Phone Ending run.
| Bucket | Cost | Rarity | Key Bonus | Best Use Case |
|---|---|---|---|---|
| Common | Free | Common | None | Early game only |
| Plastic | 200 Gems | Common | +5% Fill Speed | Budget early upgrade |
| Metal | 500 Gems | Uncommon | Improved drain efficiency | Mid-game consistency |
| Magnet | 1200 Gems | Rare | Attracts nearby items | Chest and gem collection |
| Toxic | — | Rare | +10% Token, 10% instant drain | Active token farming |
| Golden | 2000 Diamonds | Legendary | Token earnings increase, best gem farming | Premium endgame farming |
| Ancient | 10 badges + group | Legendary | +10% Token, higher-tier gem digs | F2P endgame farming |
| Toilet | Wheel Spin | — | Unique cosmetic | Collection/bragging rights |
| Use the Bucket | Wheel Spin | — | Unique special | Wheel Spin exclusive |
For a Phone Ending run, the Toxic Bucket offers the best value for active players due to its instant drain proc, while the Golden and Ancient Buckets provide the highest sustained token income. The Magnet Bucket is excellent for mid-game gem accumulation but falls off in raw token generation compared to Toxic or Legendary options. The Wheel Spin buckets (Toilet Bucket, Use the Bucket) are cosmetic novelties and do not outperform functional buckets for progression.
Badge Progression for the Phone Ending
Several badges directly support your Phone Ending run by providing Gem rewards used to purchase better buckets. Below are the most relevant badges organized by rarity tier.
| Badge Tier | Count | Gem Range | Notable Badges for Phone Run |
|---|---|---|---|
| Common | 8 | 10 Gems each | First Drop, Plunge, Shark Bait |
| Rare | 10 | 10-20 Gems | Deep Dive, The Mines, Fire Below |
| Epic | 6 | 20-30 Gems | Ancient Ruins, Into the Abyss |
| Legendary | 6 | 50-200 Gems | Find My Phone, Fully Trained, Bottomless Treasure |
Easy badges like First Drop (drain your first bucket, 10 Gems, earned by over 10M players), Plunge (swim in the lake, 10 Gems), and Shark Bait (get caught by a shark, 10 Gems) provide quick Gem income early in your run. The total Gem pool from all 30 badges exceeds 830 Gems — enough to purchase the Plastic Bucket (200 Gems) and Metal Bucket (500 Gems) with Gems to spare. Reaching 10 badges unlocks the Ancient Bucket requirement (along with joining the IWTM10GTMPLS group), making badge hunting a dual-purpose activity. The rarest badge, Ocean's Worst Nightmare, has only been earned by 56 players and is not required for the Phone Ending.
Post-Ending Content
After reclaiming your phone, the game continues with:
- Ongoing token income from your optimized loop
- Remaining badges to collect for the Ancient Bucket (if not yet unlocked)
- Additional badge hunting for completion, including the Fully Trained badge (fully upgrade Skill Tree)
- Skill Tree maxing toward the Fully Trained badge
- Exploring all depth zones freely with no pressure to push deeper
- Farming the Abyss at 8-12x multiplier for maximum token generation
- Investing in Automation now that your active loop is fully upgraded
The post-ending phase shifts the priority order. With Depth Unlock maxed, invest surplus tokens into Automation for idle token generation while offline. The spend-immediately principle still applies — hoarding tokens provides no benefit. Players pursuing the Fully Trained badge must max every Skill Tree family, which requires substantial token investment even at Abyss farming rates.

FAQ
Can I reach the Abyss without the Ancient Bucket? Yes — the Ancient Bucket makes progression faster but is not required. A strong Skill Tree and any mid-tier bucket can get you there. The Toxic Bucket's +10% Token earnings and instant drain proc make it a strong alternative for active players. The Metal Bucket suffices for reaching the Abyss if your Skill Tree levels are high enough. Legendary buckets reduce total playtime but are not gated behind any depth requirement.
What is the 62% win rate about? The Find My Phone badge has been earned by 62% of players who have played significantly, making it an achievable but meaningful milestone. This percentage reflects players who have engaged with the game beyond the initial session. The relatively high completion rate suggests that the Phone Ending is designed as the primary narrative conclusion rather than an obscure secret ending. Compare this to badges like Ocean's Worst Nightmare (56 players) or Bottomless Treasure, which have far lower earn rates.
Do I lose progress after the phone ending? No — everything is preserved. You keep all upgrades, buckets, badges, and currencies. The game continues normally after you pick up your phone. Your token multiplier at the Abyss remains 8-12x, and you can continue farming, upgrading, and collecting badges. There is no New Game+ or reset mechanic tied to the Phone Ending.
Should I invest in Automation before reaching the Abyss? Generally no — Automation should be the last priority. The upgrade order Fill Speed → Capacity → Token Multiplier → Character/Movement → Depth Unlock → Automation ensures your active loop is optimized first. Automation generates tokens while offline, but the rate depends on your active loop's strength. Investing in Automation too early yields poor returns because the idle generation scales with your other upgrades. Only after your active loop is strong and Depth Unlock is maxed should you shift tokens into Automation.
Are there any working codes for free rewards? As of July 2026, there are no verified codes for Drain the Lake. Codes are expected to be distributed via the official Discord server and the IWTM10GTMPLS Roblox group after future updates. Avoid clicking on unofficial code lists or YouTube videos claiming to have working codes — these are typically outdated or fabricated. When codes are released, they will likely provide Tokens, Gems, or possibly exclusive bucket skins.
