You have 3 lives and they regenerate on their own: one every 20 minutes, so it's enough to come back a little later. And there's a gift for coming back each day.

By playing. Each level gives coins according to the stars you earn, and there's a gift for coming back each day. Coins are used to unlock hammers, repair them and buy extra moves when you run out.

Every hammer strikes differently: it has its own wave pattern, its force and its colour affinity. You start with the starter hammer and unlock the rest with coins; there are 51 across Common, Rare, Epic and Legendary. They wear out with hits: when they are worn out you have to repair them with coins from the hammer gallery, or switch to another one and keep playing.

You tap a crystal and a wave goes out that breaks the crystals sharing a side. The wave loses power as it travels and as it passes through each crystal, and it dies out when it runs out. Shiny crystals break with the wave; dull ones are harder and need a direct tap. The goal is to clear the board without running out of moves.

If we ever add ads or purchases inside the game, we'll announce it here and inside the app itself, and this page will be updated before they appear.

From the game's Settings. The game sends anonymous statistics (an installation identifier and events such as levels played, how long sessions last, coins or lives) to know whether it works and what's worth improving. If you turn it off, it stops sending them. The privacy policy has all the details.

In Settings there's an option to clear progress. It will ask you to confirm twice, because it erases levels, lives, coins and hammers, and it can't be undone.

Write to us and tell us what happened, on which level and which phone you're using. If you know the game version, even better. With that information we can reproduce almost any bug.
