Drill That Gold on 777ad takes you underground where the real money is buried. The deeper your drill goes, the bigger the multipliers get. It's a slot game built around a simple idea — keep drilling, keep winning — and it delivers on that promise with every spin.
Drill That Gold is a mining-themed slot game available exclusively on 777ad that combines the familiar mechanics of a reel slot with a vertical drilling progression system. Instead of just spinning and hoping for matching symbols, you're actively drilling through layers of earth — and each layer you reach unlocks higher-value symbols and bigger multipliers.
The game is set in an underground mine where your drill rig sits at the top of the screen. Each spin advances the drill deeper into the ground. The surface layers contain common ore symbols with modest payouts, but as you drill further down, you start hitting gold veins, diamond deposits, and eventually the legendary Gold Core — the jackpot zone that sits at the very bottom of the mine.
What makes Drill That Gold stand out on 777ad is the tension it builds. You're always one spin away from either hitting a rich vein or triggering a cave-in that resets your depth. That push-and-pull between going deeper and cashing out is what keeps players coming back to this game session after session.
The game runs on a certified RNG, so every spin outcome is completely random. The drilling depth mechanic is a visual layer on top of the standard slot engine — it doesn't change the underlying fairness of the game, but it makes every spin feel like it matters more than a standard reel spin would.
Every layer in Drill That Gold on 777ad has its own symbol set, multiplier range, and risk profile. Here's what you'll find as you drill deeper.
The starting zone. Common rock and copper symbols appear here. Low volatility, steady small wins. Good for warming up your session without burning through your balance.
Silver ore and iron symbols start appearing. The drill speed increases visually. Wins become slightly less frequent but noticeably larger when they land.
This is where most 777ad players aim to reach. Gold nugget symbols dominate the reels. The free drill feature can trigger here, giving you extra spins without advancing the cave-in risk counter.
Diamond symbols unlock here alongside the Dynamite Blast bonus. When Dynamite lands, it clears a section of the reel and replaces it with high-value symbols for the next three spins.
The deepest and most rewarding layer on 777ad's Drill That Gold. The Gold Core symbol activates the jackpot round. Reaching this layer requires surviving the cave-in risk on every spin from Layer 3 onwards — but the payoff is worth it.
RTP figures are calculated over millions of spins. Individual session results will vary.
Drill That Gold on 777ad is a medium-to-high volatility game. This means wins don't land every spin, but when they do — especially in the deeper layers — they tend to be meaningful.
Players who prefer steady, frequent small wins may find the surface layers more comfortable. Players chasing big payouts should aim to reach Layer 4 and Layer 5 where the real multipliers live.
Drill That Gold is one of the more approachable games on 777ad despite having a layered progression system. The core loop is simple — spin, drill deeper, collect wins. The depth mechanic adds excitement without adding complexity.
New players on 777ad often make the mistake of betting too large too early. Because the big multipliers only appear in the deeper layers, you need enough balance to survive the lower layers first. Starting with smaller bets and building up as you drill deeper is a much more sustainable approach.
The cave-in risk indicator sits in the corner of the screen and increases with each spin once you pass Layer 2. Keep an eye on it — when it gets into the red zone, you have a decision to make: cash out your current depth winnings or keep drilling and risk losing your progress.
Registration takes under two minutes. Once you're in, head to the Drill That Gold game from the main lobby or directly from the navigation menu.
Use the bet controls to choose your stake per spin. 777ad's Drill That Gold accepts bets from 10 BDT up to 5,000 BDT per spin. Start conservatively until you understand the cave-in rhythm.
Each spin moves the drill one level deeper. Matching symbols on the reels pay out according to the current layer's paytable. The deeper you are, the more valuable the symbols become.
Landing three or more Dynamite symbols triggers the Blast Bonus. In Layer 3 and below, the Free Drill feature can activate, giving you additional spins at the current depth without increasing cave-in risk.
Once you've accumulated winnings, you can withdraw to your bKash or Nagad account at any time. 777ad processes withdrawals quickly — most players receive their funds within minutes of requesting.
Land three or more gold vein symbols to trigger Free Drill mode. You get 8 free spins at your current depth, with all wins multiplied by the layer bonus. Cave-in risk does not increase during free spins on 777ad.
Three Dynamite symbols anywhere on the reels triggers the Blast Bonus. A section of the reel grid explodes and is replaced with symbols from the next layer down — giving you access to higher-value symbols without actually drilling deeper.
In the Diamond Pocket and Gold Core layers, consecutive winning spins trigger a cascade multiplier. Each back-to-back win increases the multiplier by 1x, up to a maximum of 10x on top of the base layer multiplier.
777ad's Drill That Gold lets you purchase a Cave-In Shield for a fixed cost before each spin. The shield absorbs one cave-in event, keeping your drill at the current depth instead of resetting. Useful when you're close to the Gold Core.
Reaching Layer 5 and landing the Gold Core symbol activates the jackpot pick-and-click round. You choose from a grid of gold nuggets, each hiding a multiplier value. The round ends when you find the "Sealed" nugget — whatever you've collected is your jackpot payout.
Set a target depth and let 777ad's Drill That Gold run automatically until you reach it or hit a cave-in. You can set a stop-loss limit and a win target so the auto mode respects your session boundaries without you having to watch every spin.
There are plenty of places to play mining-themed slots online, but 777ad offers a combination of things that most platforms don't. First, the BDT payment system means you're depositing and withdrawing in your own currency with no conversion fees eating into your winnings. bKash and Nagad deposits are instant, and withdrawals typically clear within minutes.
Second, 777ad's version of Drill That Gold includes the Cave-In Shield and Auto-Drill features that aren't available on every platform. These tools give you more control over your session, which matters a lot in a medium-high volatility game where variance can be brutal if you're not managing it actively.
Third, 777ad runs regular promotions tied specifically to Drill That Gold — deposit bonuses, free spin packages, and cashback offers that apply to this game. Checking the promotions page before you start a session can meaningfully extend your playtime without any extra cost.
Create your free account, deposit using bKash or Nagad, and take your drill underground. The Gold Core is waiting — and it won't dig itself.
