Recently became aware of Minedustry. Looks interesting.

What type of game are you looking for? I’ll always recommend Shattered Pixel Dungeon for turn based roguelike.

Also some games I tend to install on every device I own are:

Crossword Puzzles by Redstone Games… good puzzles, simple Ui, minimal ads

Simon Tatham’s Puzzles by Chris Boyle… excellent port of many classic logic puzzles, no ads

250+ Solitaires by Alexei Anoshenko… many great solitaire games, minimal ads

For a chill puzzle game, I’ve been enjoying the water sort puzzle from Martin Kunze. I like that version specifically because there’s no ads, no monetization, no data collection, no login, no nothing. You just sort colored water until it stops being fun.

Sword of Convallaria, it’s a gacha game, but the gacha is probably least intrusive i ever seen in similar games, and it actually have entire story mode that you can play for free with barely even engaging in main mode since it have separate character pools. It’s also heavily modelled after Final Fantasy Tactics and imo managed to keep the vibes and feeling better than any other similar game.

I’ve been playing the crap out of Block Blast! Hit 406,492 for a high score so far!

Xeonjia, It’s on fdroid.

Im surprised no one had mentioned Fallout Shelter. Its the only mobile I’ve played other then angry birds.

Unciv. Basically civ V on mobile.

It’s very questionable in terms of copyright, though

Underhand is a nice little resource management game.

• Shattered Pixel Dungeon. So perfectly balanced and updated regularly, and COMPLETELY free. Also massively addictive for a long time.

• Occidental Heroes. Tricky but fun once you have the knack for it. Equal difficulty to SPD.

• Choice of Games/Hosted Games. These are platforms for publishing text based Choose-Your-Own-Adventure stories. Not all of them are free, but they’re cheap and have huge replayability. Some of their leading CYOA games are the Infinity Saga (not marvel, lol, it’s like a Napoleonic war fantasy theme) and Creme De La Creme.

• I liked Merchant too but it’s a time hog and an idle game so its arguably built just to waste your time.

Melvor Idle gives a good taste with its demo. It’s based on Runescape, but an idle version.

Mindustry, great open source game. Although it was so addictive I ended up deleting it. Now I don’t have any games on my phone.

Open Sudoku you can download thousands of new puzzles.

Legends of runeterra has a single player campaign that is probably the funnest card game ive ever played. There are in app purchases, but ive been playing off and on for about 6 years and ive never bought anything. No ads either. Rogue card adventure i think is another really good one despite the less than impressive name.

Optionally, its fully possible to get an emulator on your phone. Id recommend a bluetooth controller (a lot of older phones wont allow wired controllers even with the adapter, but ime every phone allows bluetooth controllers) but its not required. You can emulate any game from atari all the way up to gamecube on the shittiest $20 walmart phone with a screen.

Finally, as long as you are on android, technically you can get almost any app for free. Super illegal and they definitely (wont) prosecute you, so i would highly advise against checking websites like apkaward, as you might find malicious programs that install fully playable games on your device, such as the amazing star wars:knights of the old republic 2 android port that can be found on that site. Fair warning though, if you accidently end up up with kotor 2 on your phone id highly recommend getting the content restored mod. It adds back in all the cut content and fixes a slee of potentially gamebreaking bugs. On current android you do have to use a conputer to install the mod, but its very easy and i can help you with that part as it is entirely legal.
