Neves review at IGN.

"(Seven spelled backwards) is a familiar real-world tile puzzle game that challenges players to piece together seven specifically shaped angular tiles to form a given shape. It's not exactly Sudoku, but it's a puzzle that's pretty popular in Japan, and it's popular enough (and lacking in intellectual property licenses) for a development team to build a Nintendo DS version for an on-the go edition. Neves is straightforward and challenging with dozens upon dozens of puzzles to solve. Its biggest problem - apart from the truly dreadful soundtrack playing in the background - is that it's priced way too high to be recommended. What's released at 30 dollars retail should really be $20 bucks maximum."
