Shape Linker is a timed matching game, featuring various geometric shapes. The first round allows over a minute and a half long, in order to get used to the mechanic of play. Future rounds drop 10 seconds off the time limit, becoming a challenging game.
In order to be a match, the two shapes must be of the same type and color, and have an "open path" between their tiles. When you make a linked match, the link will be shown and then the tiles removed.
You also get some help along the way. You can use the REFRESH button 3 times, this mixes up the game cards so it is easier to find linking matches. You can also use the FIND button 3 times, and this will find the matching links for you. It is recommended that you use these features in early rounds, because you will not have time in the more advanced rounds.
Shape Linker is an addictive race to find the matching links, that gets harder each round. Paid version does not have advertising.
