KnobPuzzle is a colorful, exciting wooden puzzle game for toddlers, aged 2-4. Help your child train motoric skills and practice colors, shapes and materials, as the knob pieces are moved around the board with an easy "drag-and-drop" movement. Each individually crafted wooden piece fits into a specified area on the board. Rich sound effects add to the joy of the game with immediate positive encouragement.
The imaginative artworks comes alive on 7 different 3D-rendered kid puzzles, with advancing difficulty. The interface is completely self-explanatory, with no buttons or switches to activate: your child merely opens the game, and the fun begins! After completing one board your child effortlessly proceeds to the next puzzle, as the game automatically activates the board to come. There are no locked levels, but all seven boards are available from the start.
