Fivelink
A daily number puzzle for Android
Every day you get a start number, a target and 5 operation tiles. Put the tiles in the right order to turn the start number into the target: you have 6 attempts, and each one shows every intermediate value, up to the result or the step where the chain breaks. A new puzzle every day at midnight, the same for everyone, entirely offline.
