Stair Ball: Hyper Casual

GameMonetize

Stair Ball is a one-thumb hyper-casual game built on a single honest rule: the ball will zig, the ball will zag, and your only job is deciding when it touches down. The ball slides itself left and right across descending stair blocks, and tapping lifts it over the gaps and spikes that start appearing from level 10 onward. What keeps it from being pure noise is the landing rule, every bounce must land flat on a stair top, edge hits send you spinning into the void, so timing your tap to the ball's position rather than the obstacle becomes the whole skill. Runs last 20 seconds, failures restart instantly, and the difficulty slope is tuned to be brutal around level 25, which is roughly where one-more-try turns into twenty-more-tries.
