Looking some simple games for kids for educational brain breaks (Phaser 3)

Looking some simple games for kids for educational brain breaks (Phaser 3).

Would like to integrate some basic activities/games for kids that run for 1 min between learning sessions. Not too addictive or violent as this will be for primary school children between ages of 4 and 8. Things like snake or tetris… that style and simplicity.

Also this is for commercial use and we have a small budget

Thanks
