The richest veins are buried deep underground. On 66zx, Drill That Gold puts you in the driver's seat of a high-powered mining rig — spin the reels, drill through the layers, and strike the gold seam that pays out real BDT instantly.
Drill That Gold on 66zx is a high-volatility slot game built around one simple idea — the deeper you drill, the richer the rewards. The game takes place across a 5×4 reel grid set against a deep underground mine, where every spin sends your drill bit further into the earth. The visual design is dark, gritty, and satisfying in a way that most slot games simply aren't. You feel like you're actually working toward something with every spin.
The core mechanic is straightforward. You spin the reels and match symbols across the paylines. But what makes Drill That Gold different from a standard slot on 66zx is the layered depth system. The game tracks how far your drill has progressed through four distinct underground layers — surface rock, copper seam, silver vein, and the deep gold core. Each layer unlocks different multipliers, bonus features, and free spin opportunities. The further you go, the more the game opens up.
For players in Bangladesh who enjoy games with a clear sense of progression, Drill That Gold on 66zx hits differently from a typical spin-and-forget slot. There's a rhythm to it. You build momentum through the layers, and when you finally crack the gold core, the payout potential is genuinely significant. The 5,000x maximum win is not just a marketing number — it's achievable through the deep gold bonus round that activates when you reach the bottom layer.
The RTP of 96.4% puts Drill That Gold among the better-value games on the 66zx platform. High volatility means wins don't come on every spin, but when they do arrive, they tend to be worth the wait. This is a game for players who are comfortable with variance and who understand that the big payouts in mining come to those who keep drilling. If you're looking for a slot that rewards persistence, Drill That Gold on 66zx is worth your time.
Drill That Gold on 66zx tracks your progress through four underground layers. Here's what each one holds.
The starting layer. Standard paylines are active, base symbols pay at face value, and the drill meter begins filling. This is where you build your momentum on 66zx before the real action starts.
0–25m depthCopper symbols appear on the reels and carry a 1.5x multiplier on all wins. The first bonus feature — the Drill Wilds — activates here, adding wild symbols that expand across full reels on 66zx.
25–50m depthSilver symbols unlock the free spins feature — up to 15 free spins with a 2x multiplier applied to every win. The drill meter charges faster here, pushing you closer to the gold core on 66zx.
50–80m depthThe deepest layer and the most rewarding. Gold symbols trigger the Grand Drill Bonus — a pick-and-win feature with multipliers up to 5,000x your stake. This is what every 66zx player is drilling toward.

Drill That Gold is a high-volatility game, which means your approach to bankroll management matters more here than it does in a low-variance slot. The game is designed to deliver infrequent but substantial wins, and the biggest payouts are concentrated in the deep gold core layer. To reach that layer consistently, you need enough spins in your session to let the drill meter fill through the earlier layers. Going in with a small balance and expecting to hit the Grand Drill Bonus on your first few spins is the wrong mindset for this game on 66zx.
A practical approach that many 66zx players use with Drill That Gold is to set a session budget that allows for at least 80–100 spins at your chosen stake level. This gives the drill meter enough time to cycle through the layers and gives you a realistic chance of triggering the silver free spins or the gold bonus round. Cutting a session short after 20 spins because you haven't won yet is the most common mistake players make with high-volatility games on 66zx.
The Drill Wild feature in the copper seam layer is worth paying attention to. When a Drill Bit wild lands on reel 3, it expands to cover the entire reel and stays sticky for the next two spins. This is the most reliable mid-game boost in Drill That Gold, and it often leads to multi-line wins that help sustain your balance while you work toward the deeper layers. On 66zx, you'll notice that many of the bigger base-game wins come from this feature rather than from standard symbol combinations.
The Grand Drill Bonus in the deep gold core is a pick-and-win feature where you choose from a grid of rock faces, each hiding a multiplier. The multipliers range from 10x to 5,000x your stake, and the feature continues until you uncover a "stop" tile. The key thing to understand is that the average payout from this bonus round is significantly higher than anything available in the base game — which is why reaching the gold core layer on 66zx is the primary goal of every session.
One more thing worth knowing: the Dynamite scatter symbol pays anywhere on the grid, not just on active paylines. Three dynamite symbols anywhere across the 5×4 grid pays 2x your total stake, four pays 10x, and five pays 50x. These scatter pays happen independently of your line wins, so they can add meaningful value to spins that would otherwise return nothing. Keeping an eye on scatter frequency is a good habit when playing Drill That Gold on 66zx.
