How do power ups work in Crosswordling?

[AARPTeri]

In Crosswordling, you have a certain number of moves before you run out and lose a life. It’s your goal to unscramble the whole crossword before running out of moves – and power ups help with that. The game has two power ups, both of which are available during each level:

1. Undo, which allows you to take back your last move. This is a great tool if you make a move that results in two gray letters that you didn’t expect.
2. Auto Swap, which automatically moves two letters, with at least one ending up in the correct place.

You will start with three of each of these power ups. Once you run out, you can get more by watching an ad (click on the power up to launch it). You can also potentially get more power ups by spinning the wheel on the game’s menu page. You get one free spin a day, which could lead to coins, powerups, or a special gift, and can get more spins by watching an ad.
