Wolfoo Blossom Garden is a free flower-linking game on a hexagonal grid: drag your finger through three or more touching buds of the same colour — the longer the chain, the bigger the flowers grow, with the last bud growing tallest. Once a flower is big enough it bursts into bloom and nudges its neighbours to grow too, setting off a bright blossom chain. Each level has its own goal: bloom a number of flowers, hit a score, break pots, clear ice or set off special flowers. 30 levels, no timer. Safe for kids 3-8.
The game suits preschoolers because its foundation is recognising colour and adjacency — the first two skills of sorting. A hexagonal grid opens six directions instead of four, so kids scan a little wider, which is good for visual attention. The blossom chain teaches a lovely piece of cause and effect: one small action can spread across the whole garden. No timer, no losing — running out of moves just means replaying the level. Free, inside the parent-controlled Wolfoo environment.
