Fill the tank exactly to the line — the empty spaces show how many more.

Rocket Fuel is an adding puzzle. Pour cans of fuel into the rocket's tank to fill it exactly to the line. A can that would overshoot is handed back, so children try combinations until the numbers add up. Fill every tank to its line and the rocket launches.

How to play

Pour cans in until the tank is exactly full. The empty spaces show how many more you need!
