A new puzzle title called Neves Plus is coming to WiiWare from Akinai Games.

Gameplay revolves around putting together basic pictures using simple flat geometric shapes, like triangles, squares and parallelograms. There are seven of these shapes, which I guess is why the game's called "neves".

Yea it's similar to doing tangrams. A trailer can be seen here:

Neves Plus will feature over 500 brain melting puzzles for you to tackle. In addition to the standard single player experience, other modes have been added, as well as multiplayer.

If you'd like a better idea of how it plays, there's a demo of an earlier DS game here.
