Puzzles
The Colour(?) Series by Bart Bonte - They're pretty fun but they are all kinda similar. Still fun though.
Cryptogram by Paul Lammertsma Dev - Has a bunch of cryptograms, it's fun.
Somnus : Nonograms by GAMEFOX - Nonograms are fun in general, but this is the one I have.
Arcades
Balls? By DaniDevStuff - you play as a circle and run into other circles and seems to be pretty long.
Cavefall by Atvis AB - You jump from side to side as you slide down a chasm. Has a story but overall the games not in-depth I guess?
Devil Hunter: Counter Attack by LoadComplete - A game about counter attacking and holding down the attack button.
Progressbar95 by Spooky House Studios - collect progress and dodge errors n stuff on a pretend desktop.
Stick Fight : Shadow Warrior by Homecooked Games - Beat up stick Figures and rise the ranks in a pretty simple game.
Stickman Bow Masters by Bazon - shoot arrows before you get shot.
That's all I have on my phone that I'd recommend, but I still got my library if you want more or hate thinking and failure.
