Tower
One button, unlimited runs — tap to drop the block. Line it up and the tower keeps its width; miss and it's trimmed. Sign in to rank your best score and keep the streak.
What counts as perfect
Tap to drop the block. Land it within six pixels of the one below and the drop counts as perfect: the tower keeps its full width and the next block moves faster instead. Miss by more and the overhang falls away as debris, and every block after that starts from whatever width is left — which is why a run usually ends in a narrow spike rather than a collapse.
Four perfect drops in a row widen the tower back out, up to the width the run started at. So the game is not only about surviving; it is about earning back the room you have already lost, against a speed that never comes down.
Signed out: the round plays here in your browser and nothing is sent anywhere — which also means it cannot be ranked, and it goes when the browser is cleared. Signing in deals it on the server, which is what makes a streak and a leaderboard place mean anything.
