Clever Alarm Clock Forces You to Play Tetris to Prove You are Awake

Battling the issue of pushover alarm clocks that simply give up attempting to wake their owners whenever said owners smash the snooze button, Instructables member nolte919 created an alarm clock that is not only persistant in attempting to get one out of bed, but does not allow an infinite cycle of hitting snooze and falling back asleep for a few minutes, and requires the snoozer to pass a test of Tetris before it shuts off.

The clock’s alarm has a user-defined snooze limit that, once reached, will not turn off until the snoozer clears four lines in a round of Tetris. The snoozer can silence the alarm for thirty seconds while playing Tetris, but if the game doesn’t detect input for thirty seconds — a period of time that isn’t long enough for a successful snooze — the alarm will sound and the process will start over. The alarm is clever in that it is persistent and also requires a snoozer to prove they are coherent before shutting off, something a snoozer probably wouldn’t be able to do if they’re stuck in the infinite loop of napping and smashing the snooze button.
