I really like this game but there’s some minor problems…

The game is great, let me start by saying that.

Pros:
- Simple mechanics
- Easy to play one-handed
- Different difficulty modes
- Guess function if you’re not sure of your options
- Fun and requires the right level of brain power while not being too difficult that it’s annoying

Cons:
- The hint function is terrible. It always gives you a hint where it isn’t useful in the slightest when you’re stuck. Some work on this from the developers would make the game a 5/5
- The ‘watch video’ for hints doesn’t work on the paid ad-free version
- I would have expected some of the ‘quick’ levels to be a bit more thought out to prevent the possibility of getting ‘stuck’ and having to guess

Definitely give it a download, it’s worth it.

Courage !

C’est dur mais je vais y arriver….

Can’t play without internet

What was a great game has been tainted. A recent update has stopped the game from working without data/wifi.

Trop de publicités

J’adore ce jeu, par contre, attendre jusqu’à une minute pour voir une publicité, c’est vraiment trop! Je démissionne 😤

Warning: ad-free breaks hints!

I really enjoy this, it’s simple and straightforward and it’s an entertaining puzzle. And I really appreciate the ad-free option so you don’t have to constantly watch ads. But one warning: if you buy ad-free, it breaks the “watch ads to get a hint” buttons, so you can no longer earn extra hints. I tried emailing the devs about this months ago and they never responded to me.
