App Name: Connector
Description: Connector is a puzzle game with a lot of challenging levels. The goal in the game is to connect the pieces, but without mixing the colors (yellow, blue, red and green). Sounds simple huh? You can rotate, select, and swap pieces from places (only those pieces with lighter background). When a piece is connected in all possible directions, its axis will be highlighted (turned on). The pro version of the game has no ads, 320 levels, 4 difficulty levels, and a maximum grid size of 9×6.
Cost: Free / $1.40 USD
