What are coins used for?

[shop555]

Just wondering what coins are used for. That don't appear to have a use as all boosts are purchased with gems.

The coins can be used on the boosts you select before starting the session.

All the boosts are purchased for gems. I'm on level 53 and havn't had a boost for coins yet. Are some charged gems and others coins or are coin boosts only on very high levels?

The Coin boosts are only available before you start a level. Mid-game or end-game boosts can only be purchased with Gems.

Frozen Turtle, could you please tell at what level one can buy coin boost before start a level? I just checked all level, everything with gems, before starting a level.

Level 42 -10,000 coins, other are gems

Im waiting for new "energy" to go to level 43...
