🍎 Make 10

Drag a rectangle around numbers that add up to exactly 10 — they vanish.

Known in Korea as the "Apple Game" — a game the whole country played at some point. One rule: drag a rectangle, and if the numbers inside sum to exactly 10, they vanish. The board keeps refilling itself, and every clear buys a little bonus time — play fast and accurately enough, and you can actually outrun the clock.
