Gridheist
A mines-style instant game. You pick how many alarms to hide, uncover diamonds to raise the multiplier, and cash out before you hit one. It runs in the browser, plays well on phones, and the top win is capped.
Demo mode only. No real-money gambling, deposits, withdrawals or prizes.
The game
A 5脳5 grid hides a number of alarms the player chooses (1-24). Every safe box raises the multiplier; one alarm ends the round. Cash out whenever you like. The more alarms, the bigger the reward per box.
Set the bet & risk
Pick a stake and how many alarms to hide. More alarms = higher multiplier per box.
Uncover diamonds
Tap boxes. Each safe box grows your multiplier and potential win in real time.
Cash out
Bank your win any time, or push your luck. Hit an alarm and the round ends.
Built for operators
