Arkadium is a ripoff.
I’m a premium player. A recent game, Merge Haven, is a gem eater! MH has competitive smaller games that don’t display correct rankings so if you think you’re in the First spot, when the game ends (like furball frenzy), all of a sudden you end up in fifth place. You can get extra points”tools” if you win these sub-games. You will spend gems to get/keep that top ranking in order to get the extra goodies. With the deception regarding the rankings, you end up spending gems you wouldn’t spend if you knew the true rankings. Ripoff games, ripoff site. Avoid.
