If you have five spare minutes, Mole Rush 45 will fill them. Everything happens on one screen with a 45-second round with 13% bomb rate, and the whole thing runs straight in the browser - no downloads, no sign-ups, no fuss.
Streaks matter: consecutive hits build a multiplier, and a bomb resets it to zero. Greedy players chase every popup and pay for it; smart ones let a bomb pop unharmed and keep the streak alive for the gold targets.
It suits anyone with a queue to wait in or a kettle to watch: students between classes, commuters, parents stealing ten quiet minutes. There is no meta-progression to lose and nothing to catch up on - a week away costs you nothing but a little sharpness.
