7 Wonders, or 7 Wonders of the Ancient World, is a puzzle game in the Match-3 genre. Players have to match runes to destroy the blocks behind them. When all of the blocks are destroyed before the time runs out, the player wins the level and moves on to the next. The theme of this game centers on the 7 Wonders, including the Hanging Gardens of Babylon, the Colossus of Rhodes, and the Great Pyramid of Giza.
Each game level consists of a grid filled with runes of various colors. A rune can be clicked and swapped with another rune to make a column or a row of three or more similar runes. The matched runes will disappear and the block behind them will change in color. Each grid block must be cleared at least once. The grid shape changes per level, which provides a challenge in clearing out blocks. To help the player along, the game features special runes and power-ups that have the ability to clear rows and columns at a time.
Players can choose from three difficulty levels. There are 56 game levels to complete in 7 Wonders. When a particular wonder is opened or unlocked in Story Mode, it would be available in the other playing modes. As the game progresses, the board size will increase, and the configuration will also change to add more difficulty.
