Free-to-play means you can play the full game without having to spend money on it! There are optional in-game purchases if you would like to progress faster, however you can certainly complete everything on your own.You can spend money on in-game coins and then use your coins to purchase more hearts, moves and boosters in order to progress faster.

We use an energy system that allows you to replay levels using your hearts (lives). Each time you lose a level, you lose a heart. Although hearts recharge every 30 minutes, you can only have a maximum of 5 hearts at a time. So if you can’t wait for 30 minutes, you can spend money on in-game coins which you can use to purchase more hearts (lives). You can also use your in-game coins to purchase more boosters and extra moves on those trickier levels ;)
