Make your own game, free
Four game builders for children aged 7 to 11. Play the game first, then build your own levels, change the rules and play what you made straight away. They run in the browser with no account and no download; a free pupil account (just a username) saves the game.

Space Shooter Builder
Fly the mission, then build your own enemy waves and power-ups.
Ages 7–11, Key Stage 2

Platform Game Builder
Draw levels with tiles, coins, hazards and enemies, then tune the jump.
Ages 7–11, Key Stage 2

Snake Game Builder
Play Snake, then change the rules: speed, walls, food and grid.
Ages 7–11, Key Stage 2

Jump Runner Builder
Jump the spikes, then build your own course block by block.
Ages 7–11, Key Stage 2
Most builders need a keyboard, so a laptop or desktop works best. Looking for something for younger children? Try the free games for ages 5 and up.
