Powder Game
Powder Game may be one of the first sand games ever made. It's still really fun but this spawned so many sand like games. There's one that may be mobile compatable here
This version actually has stick people and a playable character you can use with the arrow keys, which I don't really see in later sand games
You can set down two player characters. P1 is controlled by the arrow keys and has a square head, and P2 has a circle head and is controlled by WASD. Pressing down makes you spray the sand type that your player has "acquired" you can see P1 getting the stone sand ability when their head turns gray. Press down to spray the sand
There is also Powder Game 2, which has more sand types, including "Ant" for some reason? Here is me creating the ant suffering vortex
Aqua Box
Aqua box is another Dan Ball classic, sell aquatic plant trimmings and fill your aquarium with tetras and various little plants.
I wish there were more than just tetras, but this is a free game, and the simple style is really gorgeous.
My lush little paradise
SlowRoads
Slowroads is an infinitely generated country road to drive down, it may be calming for people who love a long slow drive
For me, it's just funny. I cannot play this game without sliding down the guardrail the entire time (skill issue) but the noise makes me laugh uncontrollably
Micro Panda
Micro Panda is a game where you run around the map and try to light up as many things as possible. Free play is really relaxing.
MONKEYQUEST
MonkeyQuest is an in-browser game where you rescue your fellow monkeys from crocodiles.. or alligators.. who have captured them, its pretty simple but the graphics are really good n cute and its fun to play for 20 minutes
SIT N SPIN ADVEWNTURE

SIT N SPIN ADVEWNTURE 2
Sit n' Spin adventure 2 is a in-browser game where you live as a sit n spin in the aftermath of the world created by the first sit n spin protagonist
FLASH GAMES
Ah flash games... a legacy that serves as a warning agaisnt proprietary file types. SO much of the free games I played as a kid where something just scratched out in flash by someone equally as bored as me.
While online emulators exist- like ruffle- I have found that none of them run original flash games as well as the OG flash player
Adobe has removed and nuked the flash player as best as they could, but you can find a non-self detonating version on the Internet Archive. You can play games by their url or download the .swf file and drag it into the program. It will run perfect!! I can't recommend it enough. (download and use "flashplayer_32_sa.exe" from this listing if it so pleases you)
STICK RPG
I cannot attest to the quality of Stick RPG, but damn is it fun to play. It's best enjoyed on a debug version of flash that you download
Interactive Buddy
THE flash game that comes to mind when I think of Flash Games.
Beat up a little gray man for cash. Or play catch with him. This one plays well in browser
