Word Finder is a blend of Boggle and a crossword puzzle. Put your vocabulary to the test by coming up with as many words as possible in the given amount of time.
Word Up
Word Up is an awesome game that borrows its main concept from the classic game Boggle. Try to create as many words as possible, and use the gold squares for extra points!
Reflector
Reflector is an awesome geometry game that’s fun as well as challenging. The first few puzzles might not give you trouble, but completing the game is not for the feint of heart.
Reorder
Reorder is not for feint-of-heart. In fact, it might be our toughest brain game. Even if you’re good enough to complete the 3×3 level, the jump to 4×4 and 5×5 can seem like an exponential increase in difficulty.

Miner Block
Get the cart filled with gold out of the mine by moving the rocks out of the way. Try your best to make as few moves as possible in order to earn the most points.
