7 Wonders: Treasures of Seven - Nintendo DS

7 Wonders: Treasures of Seven is a tile-matching game, where the player swaps adjacent runes on a grid, making matches of three or more to remove them. The remaining pieces move downwards, occupying the vacant spaces. A water column at the right side shows the time left to complete each level. The objective is to destroy the stone background by making matches over it. The pieces of broken stone fall on the field, where workers collect them to construct a monument.

After removing all the background stone, a key 7 piece appears on the grid surrounded by an outline. It can only move within the limits of the closed lines, and the player must make it fall inside a specific glowing slot, guiding it by making matches and turning the whole grid on its sides. Two arrows at the top allow the grid to rotate 90º to the left or right side.
