if you like head to head stuff, I play Clash Royale. Very different from clash of clans, basically you battle on a board and place units and spells (all the same ones from CoC) and fight each other with your units to try and take the others base. The catch is that you only get 10 cards to choose from, each card being a troop/troops, or a spell. It's very competitive with over a hundred cards to unlock, and the progression is a bit slow but extremely fun trying out new decks and card combinations.
