Futoshiki ($0.99) is a new logic game for Kindle from Braintonik Games, the makers of Strimko. I have to admit I am a sucker for this type of game, so I've already downloaded it and played thru one game. It's a lot like Sudoku (but with a field of 5 or 7 and only one square), but with additional rules, where some blocks must be greater or lesser than the ones immediately adjacent to them. Definitely worth a buck and I've got 29 puzzles to go, just on the easy mode.
Book Description
Futoshiki is a Japanese number logic puzzle.
The rules of Futoshiki are deceptively simple but the game is challenging and addictive. Each row and column must be filled with unique numbers. However, Futoshiki has a twist. It adds greater-than or less-than signs between some cells. You must honor these signs in order to solve and complete the puzzles.
This collection of 120 puzzles is grouped into four different sets ranging from easy to expert. The grids are 5x5 in easy, medium, and hard modes. Expert mode holds thirty 7x7 puzzles. The game features annotations to help you keep track of possible solutions, and a hint function to help you keep playing if you get stuck.
