Introducing

“Project Genius has managed to stuff a massive amount of gameplay, strategy, and style into those four little blocks, and they’ve got a real winner on their hands here.”

“What I like about Brainstring Advanced is that being able to see inside the toy gives you a tiny mental boost, as if by seeing the inner workings you might be able to figure it out faster.” 

“You can spend hours trying to solve this puzzle and not even come close to solving it-and that's the fun of it . . . it can also provide a fun way to strengthen your motor skills!”

“Do you and your child love brain teasers? Then you are sure to love Constantin Puzzles. These are unconventional designer puzzles that challenge your mind all while entertaining you in play.”

"A good size puzzle to introduce children to the world of brain teasers, puzzles and logical thinking . . . A great way to challenge yourself (and your friends) and keep your brain active."

“IcoSoKu combines the deduction of placement puzzles like Minesweeper or Blackout! with the mathematical puzzling of a magic square or a Sudoku puzzle.”
