About this game

Two buggies, one red and one blue, face each other in a small arena with padded walls and a crowd behind the fence. Each driver sits up in a helmet. Hit the other driver's helmet with any part of your buggy and you win the round. If your own helmet hits the floor, you lose it.

Each player has two buttons: hold one to drive left and the other to drive right. Driving forwards lifts the front into a wheelie, and reversing brings it back down. The buggies are on springs, so they bounce and go up in the air. In the air the same two buttons tip the buggy round, so you can land on your wheels, or on the other driver.

A roll bar guards the front of each helmet, so driving straight at each other doesn't win. You have to come down on top, get round behind, or ride up over the other buggy. When someone is bonked, the game goes into slow motion, their helmet flies off and the crowd jumps up.

Every round is in a different arena, and a match goes through all seven in a shuffled order before any comes round again:

• Little Planet: a small planet in space. Gravity pulls towards its middle, so you can drive all the way round it, and the other buggy can come over the top at you.
• Moon Bubble: two ramps throw the buggies into a big bubble in the middle, where gravity is weak and they float.
• Flip Side: a floor and a ceiling. Every 7 seconds, after a warning beep, gravity turns upside down and both buggies fall to the other side.
• The Dip, The Hump, The Seesaw and Spring Pads: a dirt half-pipe, a hill that throws you into the air, one long plank on a pin, and a floor with two springs in it.

After 20 seconds the walls start to close in. Pick best of 3 or best of 5 on the start card.

Hold the phone sideways, with Red at the left end and Blue at the right. It still works with the phone's rotation lock on. On your own, you play Red against the computer. It is quick to land on its wheels but slow to make up its mind on the ground, and it can be beaten.

Good for

• Two children sharing one phone or tablet
• Wet play, when the class can't go outside
