Shapecraft by Gamezaur $1.99

 Shapecraft comes from Gamezaur. It's a minimalist puzzle. Which means that the rules are never explained. Essentially, it's a packing puzzle and the dots on the pieces must fit onto the dots on the grid.

There's a lot to like about this game.
1. The graphics are outstanding.
2. Level 51 introduces a new concept: some blocks can change color.
3. Some colored pieces, say blue, are not directly connected, but they travel together.
4. The images show just dots, however there are also squares & triangles.
5. When the pieces are outside the grid, they're easy.  But when the pieces are on the grid, shifting them around can be a very crowded job. 
6. There are 84 levels, I did them over 2 days.  This is a very relaxing puzzle. A winner.
