Every round begins with several turtles scattered across the bathroom floor. All turtles have a number from 1 to 9 on their backs. The players need to find number pairs that add up to 10, e.g. the turtles with the number 3 and turtles with the number 7 on their backs. The players then need to place all the turtles with the number 3 and the number 7 inside the toilet bowl. The players move the turtles by dragging and dropping them with their fingers. Once the players have managed to put every single one of the turtles belonging to this number pair into the toilet, the toilet will flush and all the turtles inside the toilet disappear. If just one of the turtles that the players placed in the toilet does not belong to the number pair, the toilet won’t flush, but instead “spit” out all of the turtles.

Time pressure & round indicator

If the players are not able to clear the round fast enough, even more turtles that need to be flushed out will automatically appear. If the bathroom floor gets flooded with turtles, the game is over, and the players will have to start the game again from round one. The white toothpaste coming out of the red tube at the bottom right corner of the screen always indicates which round the players are currently playing.
