The fastest way to get tokens is definitely Patchwork. Itís a bit slow at first. You get one token for every 10 puzzles beat. After you beat them all, you unlock challenge mode. This gives you a random puzzle and if you beat it before time runs out, you get a token. I played the easy, 30 second challenges over and over and racked up dozens of tokens. There is no limit to how many tokens you can get and it doesn't matter if you've previously cleared that puzzle in challenge mode. If you are good at it, you can get a token every minute or so.
