A slithering snake of numbers is making its way around a maze of ramps, and only you can stop it from getting away.
As the line of balls – numbered from 1 to 12 – works its way around the ramps towards a hole for them to drop through, you can remove individual numbers by firing another ball at the line.
If the number you fire collides with another number that together multiply to 12, both disappear. Hit several of the same right number with your ball and the whole line disappears. If that brings numbers on either side together that also multiply to 12, they too disappear, building up your score even further. Clever players can push their score higher by planning for these collisions.
Useful for children aged 7 to 11, this also teaches hand-eye co-ordination as you try to make sure your aim matches the movement of the numbers. Take careful aim, and let fly!
