Inspired by the Dobble card game, a friend and I built an iOS version where the symbols are emojis! You can customize the difficulty with options like “only green emojis” or other themed sets.

We don’t want to put ads in the game, but we’re exploring ways to add non-free features to make a little money from it. Has anyone done something similar? Any insights or past experiences with monetizing a casual mobile game would be really helpful!
