Drag apples into either basket. Take apples out, or move them to the other side. When both sides have the same number, the machine settles and the bell rings. There is more than one way. You can keep playing after it balances!

Try touching the baskets, pointer, gears or the little engineer.

Keyboard: choose an apple below, move with the arrow keys, then press Space to let go. Escape puts it back. Or use a basket button.
