Worth a try, and worth 1$ – Boxy Kingdom Review

Making any purchase removes ads permanently. I bought the rat king for 1$ and I didn't regret it. The game is a great time killer to play between doing other things, and there's enough variety in characters to provide something for everyone. The majority of characters can be unlocked with gold, though which one you get is random, so it is kind of a crapshoot. As a F2P game, 4 stars. As a freemium game, easily a 5.
