How to Play:
Gamdom Crash
Crash is one of the most popular Gamdom Originals. Its exciting, fast-moving pace keeps players gripped as they must decide when to cash out before the crash.
The game starts with a 1.00x multiplier, which increases as the moving icon (the crash object) moves along the screen. Players can cash out at any time, banking their profits from whatever the multiplier was at that point. However, if the crash happens before you cash out, your entire bet is lost.
- RTP: 100.0%
- House Edge: 0.00%
- Max Win: Up to 1,000,000x
- Pace: Fast (Rounds every 10 seconds)
How to Play:
- Bet: Place your bet during the ‘betting window’.
- Watch: A rocket takes off, and the multiplier increases (1.00x, 1.01x, 1.10x, 2.00x, 10.00x, and so on).
- Cash Out: Hit the ‘Cash Out’ before the rocket crashes. If you wait too long, you lose the bet.
Gamdom Dice
Dice games have been around for centuries, but Gamdom Originals Dice puts a new spin on this old classic. It uses a virtual 100-sided dice. Players use the slider to set a number between 0.02 and 99.98, and then decide whether to bet over or under. Dice is a favorite for players who use automated betting scripts or the Martingale strategy.
- RTP: 100.0%
- House Edge: 0.00%
- Win Chance: Adjustable (0.02% to 98%)
- Max Payout: Up to 4,950x
How to Play:
- Set Slider: Move the slider to set your target win multiplier (e.g 2.00x or 100.0x).
- Prediction: Bet on whether the roll will be Over or Under your target number.
- Roll: If the dice throw lands in your green zone, you win instantly.
Gamdom Roulette
It’s roulette, but not as you know it. There is no wheel; instead, the user interface displays the numbers on a horizontal ticker. Gamdom Originals Roulette has 101 numbers: 1 - 50 are red, 51 - 100 are black, and green is 0.
The betting options are simplified. Players can only wager on one of the three colors. You cannot bet on single numbers, odd/even, or dozens like you would on a regular table.
- RTP: 100.0%
- House Edge: 0.00%
- Max Payout: 2x for red/black bets and 100x for green
How to Play:
- Bet: Select the color you want to bet on.
- Roll: Wait for the spinning ticker to stop. The color/number that stops on the center marker is the winner.
- Payouts: Winning bets are instantly credited to your account balance.
Gamdom Hi-Lo
Hi-Lo is a simple game in which players bet on what the next card will be. This variant is automated, with a new card being drawn every seven seconds. The primary bets are Hi or Lo. These have dynamic payouts that adjust depending on the value of the previous card.
Other betting options include red/black, clusters (2-9, J,Q,K,A, or K,A), and the Joker, which pays 999x your bet amount.
- RTP: 100.0%
- House Edge: 0.00%
- Max Payout: Up to 999x
- Pace: Very fast
Gamdom Limbo
Limbo shares similarities with Originals Dice, but the payout potential is far higher. This variant has a max win of 10,000,000x times your bet, although the maximum payout is capped at $1,000,000.
Gameplay is simple. Players select their target multiplier and enter their bet amount. Following that, they click roll. If the outcome is above the selected target multiplier, your winnings are credited instantly to your account balance. Read our

Gamdom Plinko
Inspired by the Japanese arcade game Pachinko, Gamdom Originals Plinko gives players a chance to win up to 1,000x their bet. Players drop a ball from the top of a triangular pyramid that’s lined with rows of pins.
As the ball falls, it hits the pins, causing it to deflect off in different directions until it lands in one of the win multiplier pots at the bottom. This game has three risk levels: Low, Medium, and High. Players can also adjust the number of rows (of pins) between 8 and 16.
- RTP: 100.0%
- House Edge: 0.00%
- Max Payout: Up to 1,000x
- Variance: Variable to suit all player types
Gamdom Mines
Mines is my favorite Gamdom Original for its nail-biting tension. Played on a 5-by-5 grid, players must decide how many mines (1 to 24) they want active across the 25 squared-tiles board.
You then select tiles, hoping to reveal a gem. With each successful click, the payout multiplier increases. Players can continue or cash out. However, if you hit a mine before cashing out, that’s your bet lost.
- RTP: 100.0%
- House Edge: 0.00%
- Max Payout: $1,000,000
- Theme: Inspired by old Minesweeper games
Gamdom Keno
Keno is a number-picking game. You can pick between one and ten from the keno board that contains 40 numbers (1 - 40). It also has four risk settings, which affect the win multipliers based on the number of matching numbers you hit.
- RTP: 100.0%
- House Edge: 0.00%
- Max Payout: 1,000x or $1,000,000
- Game Type: a hybrid between lottos and bingo
