Nums to One: Make 24 & More

Nums to One is a number puzzle: merge four number cards with + − × ÷ until one card is left — the target. Make 24, and more.

Tap a card, an operator, then another card. The two cards fly together and become one. Three merges, one target. Easy to learn, surprisingly deep.
