Drill That Gold at kt444 puts you in the driver's seat of a high-powered mining drill, boring through layers of rock and earth to uncover gold veins, gem deposits, and explosive bonus chambers. The deeper you drill, the bigger the rewards waiting underground.
Drill That Gold takes a concept that's immediately satisfying — digging through the earth to find treasure — and builds a genuinely deep slot experience around it. The game runs on a 5-reel, 4-row grid with 1,024 ways to win, but what makes it stand out from standard slots is the Drill Depth system that runs alongside the base reels.
Every spin advances your drill one level deeper into the earth. The deeper you go, the richer the ore deposits become, and the higher the multipliers attached to the symbols on that depth level. At surface level you're finding basic rock and low-value minerals. By the time you reach the sixth depth layer — the Gold Core — the multipliers on winning combinations are dramatically higher than what you'd see in a standard slot.
The Dynamite Bonus Round is the headline feature. Land three or more Dynamite Scatter symbols anywhere on the reels and you trigger an underground explosion sequence that clears a section of rock and reveals a hidden prize chamber. These chambers contain free spins, instant cash prizes, or the Molten Gold Jackpot — a progressive prize that builds across all kt444 players spinning Drill That Gold simultaneously.
kt444 has configured Drill That Gold with Bangladeshi players specifically in mind. The minimum bet of ৳150 per spin makes it accessible for casual sessions, while the maximum bet of ৳300,000 per spin gives high-stakes players the room they need to chase the bigger multipliers at deeper drill levels. All transactions run in Bangladeshi Taka with no conversion fees.
Each spin takes your drill one layer deeper. The rewards grow with every level — here's what you'll find as you bore through the earth at kt444.
* Drill depth resets to Layer 1 after triggering the Dynamite Bonus Round. Each new session starts fresh from the surface.
Beyond the base reels, Drill That Gold at kt444 packs in several mechanics that keep every session feeling different from the last.
Every spin advances your drill one layer deeper. Multipliers scale with depth, so the longer your session runs without a bonus reset, the more valuable each winning combination becomes.
Three or more Dynamite Scatters trigger an underground explosion sequence. Rock layers are blasted away to reveal a hidden prize chamber containing free spins, cash prizes, or jackpot access.
The Wild Drill symbol appears on reels 2, 3, and 4. At deeper layers it expands to fill the entire reel, creating massive win combinations across all 1,024 ways simultaneously.
A progressive jackpot that builds from a percentage of every bet placed on Drill That Gold across all kt444 players. Only accessible when your drill reaches Layer 6 — the Gold Core.
Free spins awarded during the bonus round play out at your current drill depth — the depth doesn't reset during free spins. If you trigger them at Layer 5 or 6, every free spin carries premium multipliers.
From Layer 4 onwards, Gem symbols appear that carry their own attached multiplier value. When a Gem lands in a winning combination, its multiplier stacks on top of the depth multiplier for outsized payouts.
Getting started is simple. The depth system adds a layer of strategy that you'll pick up naturally after a few spins — here's the full picture before you begin.

The single most important thing to understand about Drill That Gold is that the depth system fundamentally changes the value of every spin. A winning combination at Layer 1 and the same combination at Layer 6 can pay out at completely different rates. This means your session strategy should be built around reaching and staying at deeper layers, not just spinning and hoping for the best.
The most effective approach for most players at kt444 is to start with a moderate bet size and maintain it consistently through the early layers. The goal in Layers 1 through 3 is simply to advance your drill depth without burning through your session budget. You're not trying to win big at the surface — you're building toward the deeper layers where the real multipliers live.
Once you reach Layer 4 or 5, this is the point where many experienced players consider increasing their bet size. The multipliers at these depths mean that a larger bet combined with a strong winning combination can produce a payout that more than covers the cost of the earlier lower-bet spins. It's a calculated approach rather than a reckless one — you're essentially treating the early spins as the cost of reaching the premium depth levels.
The Dynamite Bonus Round timing matters more than most players realise. If you trigger it at Layer 2 or 3, the free spins play out at that depth — decent, but not exceptional. If you can hold out and trigger it at Layer 5 or 6, those same free spins carry the full premium multipliers of the deeper layers. The difference in payout potential between a Layer 3 bonus and a Layer 6 bonus is substantial.
The Molten Gold Jackpot is worth keeping in mind if you're a regular kt444 player. Since it's progressive and builds from all players' bets, it can reach significant amounts before being claimed. The jackpot is only accessible at Layer 6, which gives you a concrete reason to push for the deepest level rather than cashing out at Layer 4 or 5. Check the jackpot meter before your session — if it's sitting at a high value, it might be worth adjusting your strategy to prioritise reaching Layer 6.
One thing that stands out about Drill That Gold compared to other mining-themed slots is how well the visual design communicates the depth progression. The background shifts from bright surface colours to darker, more dramatic underground tones as you drill deeper, and the symbol designs change to reflect the ore type at each layer. It's a small detail, but it makes the depth system feel tangible rather than just a number on a meter. kt444 has done a good job of presenting this game in a way that makes the mechanics intuitive even for players who haven't tried a depth-progression slot before.
