BuilderTots
A first building game for ages 3-5: Timber the beaver builds cozy things from parts! Each thing has a little recipe - a birdhouse needs 2 logs and 1 leaf. Tap the piles to gather the right number of each part, then tap Build. No reading needed (tap to hear it), no score, no losing - just a workshop full of things you made.

Meet the cast
BuilderTots's cast is Timber the beaver and the workshop of things he builds. Timber shows the recipe, counts each part, and cheers every finished thing. Illustrated portraits & chapters are a paid-gen follow-on (STORY-PEND).
