To play Wobble Squabble, you need a ticket. The tickets are the same ones that can also be used to dive in the Lidos.

When you have a ticket, you can climb on the inflatables to queue for your turn. The game starts when two players are ready, one at each end.

You can play with the same ticket until you're knocked off by your opponent.

When the game starts, you see a window (see the picture below). On the right is a balance meter. When the hand points straight up (like in the picture), you're perfectly balanced. When it points to the right, you need to balance to the left, and vice versa. If the hand drops too far to either side (so it's horizontal), you'll fall into the water and lose.

If you are wobbling all over the place, you can get your balance back once during the game using the 'stabilise' button (space bar).

The aim of the game is to balance on the inflatables and make your opponent fall into the water by pushing them. You can move towards or away from them - you win by staying on the inflatables while your opponent falls into the water. The loser will be replaced by the next player in the line and the winner carries on playing until he/she falls in the water.

If you're both really good, the game will end when the time runs out (after 90 seconds). If neither player has fallen off by then, the one who has been pushed the most will fall off and lose.
