Playtomo is a pack of 20 casual games that all have that bubbly/Japanese style look and feel that works great. The games are things like solitaire, brick breaker, Pac-man, Doodle Jump, etc. They’re all simple knock offs but it works and there is something to having one app that’s filled with a bunch of games. And the developer states that it will continue to get more games over time and since it’s available for other platforms already, that’s likely. It also has online leaderboards and ties into Facebook.
It loads a bit slow initially but the game play is straight forward, the games are well made casual/classic titles and you can’t beat the price so give it a go.
