Drain the Lake Gem Farming Tips — Quick Strategy Overview for Beginners

Gems are the secondary currency in Drain the Lake, primarily used to purchase buckets from the shop. Unlike tokens which flow continuously from draining, Gems come from specific sources: badges, chests, and potentially codes. This guide covers quick beginner strategies for earning Gems and simple spending priorities. For a detailed, data-driven analysis of Gem earning rates, depth-scaled chest values, and ROI comparisons, see our Gem Earning Strategy.

All Gem Sources

Key insight: Badge rewards are the most reliable and predictable source of Gems. Each badge awards a fixed number of Gems, and many are easy to earn early in a session. Chests provide supplemental income but are RNG-dependent, while codes remain unconfirmed as of July 2026. Prioritize badge completion before relying on chest randomness for your Gem income.

The total Gem economy is designed so that dedicated players who earn all 30 badges can afford the Plastic Bucket and Metal Bucket purely from badge rewards, with leftover Gems contributing toward the Magnet Bucket. Chest finds and any future codes serve as bonus income on top of this foundation.

Badge Gem Rewards Breakdown

Earning all 30 badges gives you over 800 Gems, enough for the Plastic Bucket (200) and Metal Bucket (500) with Gems left over. The distribution is heavily weighted toward Legendary badges, which account for roughly half of all Gem rewards despite comprising only 20% of total badges. This means late-game badge completion delivers disproportionately large payouts, incentivizing players to push toward the deeper checkpoints where Legendary badges like Find My Phone and Fully Trained are earned, which you can read more about in our Phone Ending walkthrough.

Common badges are trivially easy—First Drop alone has been earned over 10 million times—and provide a quick 80 Gem boost for new players. Rare and Epic badges require moderate effort, while Legendary badges demand significant progression through the Phone Ending.

Badge Hunting Guide

Not all badges are equal in effort or reward. This section breaks down the most efficient badge targets for Gem farming.

Easy Badges for Quick Gems

These three badges can be earned within the first few minutes of gameplay. First Drop is automatic—simply drain one bucket of water. Plunge requires jumping into the lake, which happens naturally during gameplay. Shark Bait requires a shark encounter, which occurs periodically; getting caught is actually easier than avoiding the shark, so simply wait near the water until one appears.

Progression Badges for Mid-Game Gems

The Rare and Epic badge tiers require reaching specific checkpoints or completing skill tree milestones. These badges award 10-30 Gems each and accumulate to approximately 300 Gems across 16 badges. Focus on reaching the Shipwreck and Cavern checkpoints first, as these unlock several Rare-tier badges while also increasing your token multiplier to 1.5-3x, accelerating all future progression.

Rare and Legendary Badges

Ocean's Worst Nightmare is the rarest badge in the game with only 56 earners as of July 2026. Its exact trigger is not fully documented, but it appears tied to an extremely rare event during deep draining. Do not factor this badge into your Gem planning—treat it as a potential windfall if it occurs.

Chest Farming Strategy

Chests appear while you drain the lake. They contain bonus Gems and sometimes rare items. Chest encounters are random, but several factors influence both their frequency and the quality of their contents.

Chest Spawn Mechanics

Chests spawn at random intervals during the drain cycle. Each time you empty a bucket at a drain point, there is a chance a chest appears somewhere in the vicinity. The probability is not publicly documented, but community observations suggest approximately one chest per 15-25 drain cycles at surface level, with slightly improved rates at deeper checkpoints.

Maximizing Chest Finds

• The Ancient Bucket digs up higher-tier gems from chests, making each chest more valuable
• Drain at deeper depths for more valuable chest contents—chests at the Molten checkpoint and below consistently yield more Gems than surface chests
• More drain cycles per minute equals more chest encounters—invest in Fill Speed and Capacity upgrades to increase your cycle rate
• The Magnet Bucket attracts nearby items including chests, reducing the chance you miss a chest that spawns slightly out of reach
• Stay near drain points rather than wandering, since chests tend to spawn close to active drain locations

Chest Value by Depth

The depth scaling for chest values mirrors the token multiplier system. Reaching the Mineshaft checkpoint (3-4x token multiplier) represents a significant inflection point where chest Gem yields become meaningfully higher. Players farming Gems through chests should prioritize reaching at least Mineshaft before settling into a chest-farming routine.

Bucket Selection for Gem Farming

Your bucket choice directly impacts Gem acquisition efficiency. Some buckets improve token earnings, while others specifically enhance chest and item discovery.

The Ancient Bucket is the best bucket for Gem farming that does not require premium currency. Its higher-tier gem dig passive means every chest you open has an elevated chance of containing Rare, Epic, or Legendary gem drops. Combined with the +10% Token earnings, it accelerates both direct progression and incidental Gem income simultaneously. However, it requires earning 10 badges and joining the IWTM10GTMPLS group, which takes time.

The Golden Bucket is technically the strongest for gem farming but costs 2,000 Diamonds—premium currency—making it inaccessible to free-to-play players focused on Gem economy. If you do acquire Diamonds through gameplay or purchase, the Golden Bucket provides the highest overall returns.

Optimal Gem Spending Order

Should you save for the Golden Bucket? The Golden Bucket costs 2,000 Diamonds (not Gems), so it requires a different currency entirely. Focus your Gems on the bucket progression above and treat Diamonds as a separate progression path.

The Spend-Immediately Principle

Never hoard Gems. Unlike tokens which scale with your multiplier, Gems have a fixed purchasing power—200 Gems always buys the Plastic Bucket regardless of when you spend them. Every moment you hold unspent Gems is a moment you are playing without the upgrade those Gems could purchase. Buy the next bucket in the priority list as soon as you can afford it.

This principle is especially important for the Plastic Bucket. The +5% Fill Speed bonus applies to every single drain cycle from the moment you equip it. Earning 200 Gems and waiting to spend them costs you more in lost Fill Speed than any potential benefit from hoarding.

Early Game vs Late Game Gem Strategy

Early Game (Surface through Shipwreck)

In the early game, badge completion is your primary Gem source. Focus on earning the three easy badges (First Drop, Plunge, Shark Bait) for an immediate 30 Gems, then progress through Rare-tier badges as you push toward Shipwreck. Your first spending goal is the Plastic Bucket at 200 Gems. Chest farming at this stage is inefficient—surface chests yield only 1-5 Gems, and your drain cycle speed is slow without upgrades.

Invest tokens into Fill Speed and Capacity upgrades following the standard upgrade priority to increase your drain cycles per minute. Faster cycles mean faster badge progression and more frequent chest spawns, both of which improve Gem income.

Mid Game (Cavern through Mineshaft)

By mid game, you should have the Plastic Bucket and be working toward the Metal Bucket (500 Gems). Chest farming becomes viable at Cavern depth (5-15 Gems per chest), and your increased drain speed from Skill Tree investments means more chests per session. Continue badge hunting—Epic-tier badges at this stage award 20-30 Gems each.

This is also the stage where the Magnet Bucket becomes worth considering. At 1,200 Gems it is expensive, but the item attraction passive saves time and ensures you never miss a chest spawn. If you have earned most available badges and need a supplemental income source, the Magnet Bucket improves chest consistency.

Late Game (Molten through Abyss)

Late game Gem income comes primarily from high-value chests at deep checkpoints and remaining Legendary badges. The Abyss checkpoint yields 25-50+ Gems per chest, making active chest farming at this depth extremely profitable. If you have the Ancient Bucket, its higher-tier gem dig passive dramatically increases the value of every chest opened at these depths.

The Toxic Bucket becomes the target purchase at this stage, providing +10% Token earnings and the 10% instant drain chance that significantly speeds up deep draining. By this point, most badges should be completed, and Gem income shifts from badge rewards to chest farming and any future code releases.

FAQ

How many Gems do I need for all Gem-purchased buckets? Plastic (200) + Metal (500) + Magnet (1,200) + Toxic (Epic tier Gems) = roughly 2,000+ Gems total. Badge rewards alone provide approximately 830+ Gems, covering the Plastic and Metal Buckets completely with leftover Gems toward the Magnet Bucket. You will need supplemental income from chests to afford the Magnet and Toxic Buckets.

Are there free Gems from codes? As of July 2026, no verified codes exist. The developer IWTM10GTMPLS is expected to release codes through the official Discord and group following future updates. When codes are released, they may include free Gems. Check our [/en/codes/](codes page) for the latest information.

Should I spend Gems on the Wheel Spin? Only after you have purchased all needed shop buckets. The Wheel Spin involves randomness and can award exclusive buckets like the Toilet Bucket and Use the Bucket, but there is no guarantee of a useful result on any given spin. Shop purchases are guaranteed and provide immediate, quantifiable upgrades. Once you own the Toxic Bucket and have no further Gem purchases available, Wheel Spin becomes a valid use for surplus Gems.

Is the Ancient Bucket worth the badge requirement? Yes. The Ancient Bucket requires 10 badges and joining the IWTM10GTMPLS group, but it provides +10% Token earnings and higher-tier gem digs from chests. This makes it the strongest free-to-play bucket for Gem farming, as every chest opened has elevated drop quality. Since you will earn badges naturally through progression, the requirement is not a detour—it simply requires playing the game. Join the group early so the requirement is already met when you hit 10 badges.

Can I farm Gems offline through Automation? No. Automation generates tokens while you are offline, not Gems. Gems only come from badges, chests, and codes. Automation is worth investing in after your active loop upgrades are complete, but it will not directly contribute to Gem income. Focus Automation tokens on Fill Speed and Capacity upgrades that increase your drain cycle rate, which indirectly improves chest encounter frequency during active play.
