Non competitive stimming iPhone games?

I need a game that is not timed and doesn't have levels. The difficulty has be consistent. I just need to stim with a game that won't stress me out. Any advice?

The closest I've found was this game that gave me 6 letters and I had to try and make as many words as possible until I gave up and the game wouldn t let me level up until I paid extra (perfect for me) but then after playing for a week it demanded I pay for it to even play at all:/

Of course, it is a mental health problem, which I do not want to deny.

I think you should seriously think of some other alternative best solution to solve such complicated mental health problems.

IPhone's are garbage. Android is better!

These should all be free. I tend to go through a lot of free iPhone apps to find relaxing games that I can play.

Crazy Wheel
- all it is, is there's a open circle split into three colors, with a little spinner going around in the middle that will be a certain color and you're meant to tap the screen once it aligns with the same circle color, then it will change colors and spin in the opposite direction. Doesn't really change speeds or anything. Quite easy and relaxing

Piano Tiles
- there's a few different games to play on this, but all of them consist of tapping the black tiles as they move down. Different games within this will have the tiles moving at different speeds, so you can just try out different ones till you find a one you like. I like playing the Arcade game, which has the blocks moving down really slow and then speeds up a little till it stays at a consistent speed. I once played for like 20 minutes straight without missing a tile, so its pretty easy. There are timed games within it but you don't need to play those ones.

Monument Valley
- there are like 10 levels, and this may be a bit more interactive than what you're looking for but I thought I'd suggest it anyways because it is a very visually appealing game, and consists of optical illusions that look super cool and kind of make your eyes find little tricks. Plus, it is still really easy. And once you've played through once, you should remember how to beat all the levels.

1010!
- the game consists of getting different shaped blocks and having to place them in the field. Filling up horizontal or vertical lines make that row or column of blocks disappear so you have more room to place once again. Blocks are given at random, so difficulty is definitely consistent and there's no levels.

ZigZag
-consists of a ball rolling on a platform that zigzags and you just have to tap the screen to change the direction the ball is rolling so it doesn't fall off.

Amazing Brick
- Consists of just tapping the screen to move a block around to avoid hitting things, while traveling upwards. I was never that good at it, but I can imagine one would find it good if they are good at it. I never got very far, but I'm pretty sure it stays consistent throughout.

Theif
- same company as Amazing brick. This one just has a little stick figure running and platforms and that goal is to consistently jump from one platform to the next. Should stay consistent

The Impossible Letter Game
- spotting the different letter in a group of letters. Personally, I didn't really like this one and didn't play long enough to be able to comment on consistency or anything

Other games I have that are pretty common that I like to play are: solitaire, minesweeper, and tetris.
