Just downloaded several completely random games off of the App Store a few weeks ago because I'd be out of town for several days without much WiFi or things to do. So here they are.

Trump's Wall
In this game you are tasked with building Donald Trump's wall. You stack randomly sized blocks over one another and try to build as high as possible without any falling. My high score is 32'. Overall this game isn't that fun. Trump has some mildly funny dialogue and there are some other neat details, at least. 5/10
Risky Road
In this game you drive a truck with a weird egg-like object in the back. You have to drive through hills, loops, jumps and other obstacles without dropping the egg. This is a mildly addicting game. All rounds of playing randomly repeat the same 10-ish different obstacle types, so you just have to learn when to accelerate so you can make it past them. My high score is 117. Solid 7/10 game.
Rolling Sky
This game is a sort of 3D runner where you move forward automatically and have to move a large ball left and right with your finger to avoid obstacles and stay on the path. Currently there are seven different levels to choose from, each with their own track designs, music and visual aesthetics. This is a 7/10 game. I'd rate it higher, but after the first two or so levels, the courses become more about trial-and-error to understand their layouts than about actual reactions.
I deleted all the other games...
