The Happy Puzzle CompanyCubeslinger Game - Fast-Paced Puzzle Challenge with 120 Multi-Level Puzzles - Race, Strategize, and Solve to Win - Solo or Competitive Play for All Ages

Brilliant, an absolute ton of puzzles / brainteasers in just one box that will keep you going for a long while. Clear instructions and nicely presented i do love this stuff. And you can play 2 players as well (i just played solo and it was enjoyable)

Really enjoyed this game, even if my wife was a 1000 times better at it than me! The early levels are just tricky enough to give a fun challenge while learning the game but wait until you start getting to levels 4 and 5... So much lateral thinking and concentration required but when you finally see the pattern it's incredibly satisfying. Super simple to learn and fun to play on your own or in a time race against an opponent. Would highly recommend for people who enjoy puzzles, sudoku or any other pattern/maths based challenges

I bought 4 games as presents for my adult children who like logical puzzle games such as Sudoku and it was a big success! The game has 5 levels of difficulty and can be played solo or in pairs. It is highly addictive and competitive - who can solve it the fastest? Level 1 takes about 10 minutes to solve and level 5 was much harder, it took about 30 minutes on the first go, but gets faster when competing against others. There are 120 different puzzles to solve. It is absolutely brilliant fun.

Nice and challenging, different difficulties. Really makes you think.
