Unchain My Heart
Unchain My Heart is a game about making chains of numbers, it’s super easy to pick up but super duper hard to put down. There is one rule to the game: numbers can be joined to other numbers one higher, or one lower than themselves. The longer the chain you make, the more points you get.
There are scoring bonuses for spanning a wider range (1, 2, 3, 4, 5, 6 is worth more than 1, 1, 1, 2, 2, 2), but that’s all there is to it.
Originally released in 2013 on iOS.
