Do you play any games on your smartphone? I'm looking for single player ones to kill some time when waiting for the bus. Ideally they should work without an internet connection, so I can disable network access for that app and play without ads.
I'm currently playing Words of Wonder, but it gets repetitive after a while.
Nobody's mentioned RollerCoaster Tycoon Classic yet, that's a good one, it's RCT2 with the RCT1 scenarios included and with a more touch-friendly interface
(OpenRCT2 exists on Android for free, but you're probably gonna have a bad time trying to play that with touch lol)
I should add a few others too probably since I do have a few other favorites
Enviro-Bear 2010 - Very funny game about a bear driving a car to collect food, was originally on PC but goes well with touch
Bacon - The Game - Decent time waster for a few minutes at a time, gets repetitive though if you play it any more than that lol
Good Pizza Great Pizza - Fun pizza shop game with an absolutely adorable art style and some silly writing
Sonic 3 A.I.R. - Widescreen Sonic 3 & Knuckles on your phone? With mod support?! Hell yeah (you'll have to grab this ROM for it to work, but that's no big deal)
Vita Fighters - Haven't played it much, but this seems like a cool mobile fighting game if you're okay with playing one of those with touch controls
SHOT2048 - Yuji Naka might be guilty of insider trading and creating Balan Wonderworld lol, but this is still a fun take on the 2048 concept
