Stack Home
Help Tucker the bear cub put everything home — sort toys by colour, then by colour and shape, count cards home 1 to 5, then play Little Solitaire (send the hearts and spades home in order). Tap a card, then tap its home; a wrong basket just says what it wants, undo is unlimited, and every game can be finished. No timer, on-device, no account. Ages 3-5.
▶ Play it nowBuilt for sittings of about 10 minutes on the screen. That is our design budget, not a measurement.

Meet the cast
Stack Home's friends each embody one SORTING RULE — the crew IS the rule ladder. Swatch matches by colour and shape, Upsy climbs home in order 1 to 5, and Zigzag the ladybug hops one lower and switches colour. Tucker the bear cub (the hero) asks where each thing belongs.

Upsy
A caterpillar who climbs home in order - 1, 2, 3, 4, 5, never skipping
