Game currency

Game currency

There are 3 types of currency in the game hub: coins 🪙, gems 💎 and keys 🗝️.

The balance is common to all games in the game hub.

So, you could play a game, close the app and then come back and play another game with the same balance.

Coins 🪙 are used for changing the difficulty of the mini-games and for switching a Hidden Object mode to a match-3 mode. Each of these options costs 15 coins.

You can get coins by watching advertisements every five minutes. You can also buy coins in the in-game store.

Gems 💎 are needed to unlock an additional chapter in the game. You can also buy them in the in-game store.


Keys 🗝️are needed to unlock new chapters inside the games. They are recovered every 4 hours, and you can also trade them in the in-game store.
