Space Tower vs SortaSize

Touch the screen to drop the block. Line up blocks carefully in order to make the tower as high as possible. Once the tower collapses the game is over.

SortaSize turns learning small-to-big into a game young children can play on their own — tap the smallest critter first, then the next size up, no dragging required. It's a simple, screen-friendly way for toddlers and preschoolers to practice size ordering, sequencing, and comparing, wrapped in a calm, colorful world. Every round adapts as your child improves, starting with 3 critters and growing to 6. There's no fail state: a wrong tap just gets a gentle nudge to try again, and every round ends in a cheerful celebration with sound and haptics. Included from the start: • Tap-to-sort gameplay — no fiddly dragging for small fingers • The Buddy world, fully playable with no purchase needed • Adaptive difficulty from 3 up to 6 items per round Unlock with SortaSize Pro: • 5 more original critter worlds • Big-to-small reverse mode for an extra challenge • One-time purchase, shared with your whole family via Family Sharing SortaSize is fully offline with no accounts, no ads, and no data collected — designed for ages 2-6, built for a parent's peace of mind and a child's delight.
