Don't Tap the White Tile

🕹️ How to play

1. Start a round: The board is ready the moment the page loads. Tap the bottom black tile marked Start — the clock starts on that tap — then keep tapping the black tile in the lowest row, one row at a time.
2. Pick a mode: Use the three buttons above the board: Classic times you over 50 tiles, Timed counts how many tiles you clear in 30 seconds, and Endless scrolls the board by itself and speeds up, with Slow, Normal and Fast starting speeds.
3. Play with a keyboard: On a computer, D, F, J and K map to the four columns from left to right — two fingers per hand works best. Holding a key does not repeat, and Esc pauses the round with a 3-2-1 countdown when you resume.
4. See why you lost: A white tile you hit turns red, and a black tile you missed is pulled back into view and flashes red, with the reason written above the board. The result card shows your score, your best and a rank; Play again deals a fresh route.

📖 Rules & variants

Basic rules: the board has four columns and exactly one black tile per row. Start from the bottom row and tap each black tile in order. Tapping a white tile, or letting a black tile slide off the bottom in Endless, ends the round at once. There are no revives, power-ups or extra lives, so every record is earned the same way.

Classic mode timing: the clock starts when you tap tile 1 and stops when you tap tile 50, measured to the millisecond. Tiles never move on their own in Classic, so kids and beginners can finish a full round at their own pace. If you hit a white tile you see how far you got, such as 37/50, and no time is recorded.

Timed mode rules: a 30-second countdown starts on tile 1, and your score is every tile you clear before it reaches zero, tile 1 included. Taps after the buzzer never count, and the readout turns red for the last five seconds. Hitting a white tile ends the round early but keeps the tiles you already cleared.

Endless mode speed: the board scrolls by itself and keeps speeding up, but the increase flattens out over time. Normal starts at about 4 tiles per second, reaches about 5.1 after 10 seconds and 6.9 after 30 seconds, and never exceeds 9. Speed depends only on game time, not on your screen's refresh rate, and each starting speed keeps its own best.

How taps are judged: a tap anywhere in the right column, on the black tile or below it, counts as a hit. In Classic and Timed the whole column counts. Tapping a grey tile you already cleared, or a black tile further up, is ignored instead of ending the round, so a shaky finger or two thumbs landing together won't cost you. Switching apps, locking the screen or rotating the phone pauses the game and hides the tiles.

Ranks and tunes: Classic ranks go by average speed — 5 tiles per second or more is Lightning, 3.5 is Quick, 2 is Steady, anything slower is Easy does it. Timed mode uses 150, 105 and 60 tiles. Every tap plays the next note of a public-domain melody, the tune changes each round, and the result card tells you which one you played.
