Block it is a minimalist arcade game about fast reflexes and clean timing.
Stop moving blocks at the perfect moment to keep the board clear and chase a new best score.
Watch the incoming block and tap or click right when it reaches the stop line to place a barrier. Time your input so the block meets the barrier exactly. Missing the moment lets the block slip through and ends the run. Stay calm, read the speed, and keep a steady rhythm as the pace increases.
Tip: look one step ahead and tap a fraction before impact to account for your reaction time.
