CrossTots
A first crossing game for ages 3–5: two picture-words meet, and one letter finishes both. Hear the words, look at the pictures, and tap the letter that belongs to both — the very first idea behind crosswords. On-device; nothing leaves your device.

Meet the cast
CrossTots has a tiny friendly crew who show how words cross: Knox is where two words meet, Exa is the shared spot, Duo is the two words, and Letty is the one letter that finishes both (their illustrated storybooks are on the way).
Knox
(Guide) the crossing — where two words meet, they share a corner
Exa
The shared spot — the one cell that belongs to both words
Duo
Two words — a letter can help two words at once
Letty
The shared letter — the one letter that finishes both words
