Monster Mine is i888's pulse-pounding take on the classic minesweeper format. Every tile you flip could reveal a glittering gem — or a monster bomb that ends your run. The further you dig, the higher your multiplier climbs. How deep do you dare to go?
21+ only. Please gamble responsibly. Gambling is addictive. Know when to stop.
Monster Mine is one of i888's most popular original games — a fast-paced, skill-influenced instant game that puts you in control of a 5x5 grid of hidden tiles. Beneath those tiles lie two types of surprises: sparkling gems that grow your multiplier with every safe reveal, and monster bombs that end the round instantly.
Before each round, you choose how many monster bombs are hidden in the grid — anywhere from 1 to 24. Fewer bombs means safer digging but lower multipliers. More bombs means higher risk, but the rewards climb fast. It's a pure tension-and-reward loop that Filipino players from Manila to Davao have fallen in love with.
Unlike traditional slots where you just spin and wait, Monster Mine gives you agency. Every tile flip is a decision. Cash out early and lock in your winnings, or keep digging for that massive multiplier. The choice — and the thrill — is entirely yours.
Live Grid Preview
Simple to learn, impossible to put down. Here's how it works.
Choose your wager — starting from as low as ₱10 per round. i888 supports all budgets, whether you're a casual player in Cebu or a high-roller in Makati.
Select how many monster bombs are hidden in the 5x5 grid. More bombs = higher risk, higher reward. Start with 3 bombs if you're new to the game.
Click any tile to reveal what's underneath. Each gem you uncover increases your multiplier. Hit a bomb and the round ends — your bet is lost.
At any point, hit the Cash Out button to lock in your current multiplier and collect your winnings. Timing your exit is the key skill in Monster Mine.
How multipliers scale based on gems revealed and bombs selected.
| Bombs Hidden | 1 Gem Found | 3 Gems Found | 5 Gems Found | 10 Gems Found |
|---|---|---|---|---|
| 1 Bomb | 1.04x | 1.13x | 1.25x | 1.72x |
| 3 Bombs | 1.12x | 1.45x | 2.10x | 5.80x |
| 5 Bombs | 1.22x | 1.95x | 3.60x | 18.5x |
| 10 Bombs | 1.56x | 4.20x | 14.0x | 200x+ |
| 20 Bombs | 4.80x | 82x | 480x | 1,000x |

More than just a mine game — it's a full adrenaline experience built for Filipino players.
No waiting for reels to spin. Every tile flip resolves in milliseconds — perfect for quick sessions between PBA games or during your lunch break in Quezon City.
You control the difficulty. Set 1 bomb for a chill, low-risk session or crank it up to 20 bombs for heart-pounding, high-multiplier action. Your game, your rules.
Monster Mine runs beautifully on any Android or iOS device. The tap-to-reveal mechanic was designed for touchscreens — smooth, responsive, and data-light for 3G/4G connections.
Every round in Monster Mine uses a certified random number generator. The bomb positions are determined before you start — no manipulation, no tricks. Pure fair play.
Win big and cash out fast. i888 supports GCash and PayMaya withdrawals — the most popular e-wallets in the Philippines — so your winnings reach you within hours.
Monster Mine carries a 97.0% RTP — one of the highest among instant games at i888. That means more value per peso compared to many traditional slot machines.
There's no guaranteed formula, but these habits separate smart players from impulsive ones.
If you're new to Monster Mine at i888, begin with 3 bombs on the grid. The multipliers are modest but the survival rate is high — great for learning the cash-out rhythm without burning through your balance.
Decide your target multiplier before flipping a single tile. If you're aiming for 3x, commit to cashing out the moment you hit it. Greed is the number one reason players lose winnings they already had.
Want to chase that 200x or 1,000x multiplier? Use your minimum bet (₱10) when playing with 10–20 bombs. The variance is extreme — small stakes let you enjoy the thrill without risking your whole session budget.
Hit a bomb and lost your bet? Don't immediately double your next wager to "win it back." That's how small losses become big ones. Stick to your pre-set budget — the same discipline that makes a good PBA bettor makes a good Monster Mine player.
i888's welcome bonus and Payday Reload Bonus can extend your Monster Mine sessions significantly. Use bonus funds to explore higher bomb counts risk-free. Always check the wagering requirements before playing with bonus balance.
