CAR JAM SOLVER
Car Jam Solver is the traffic-jam puzzle a lot of people know from the app stores, and this is the same game running in a browser tab. No install, no account, and it saves your progress locally so you can come back to the level you were on.
The setup is always the same: a lot of cars packed into a small area and one of them needs to get out. Tap a car and it drives in the direction it's facing until something stops it. If the way is clear it leaves the board; if it isn't, it bumps into whatever is in front and you've used a move for nothing. The whole game is working out which cars to send first so the others have room.
The first twenty or so levels teach you the basics without much resistance. After that the boards get crowded, cars start facing awkward directions, and you'll find yourself staring for a bit before touching anything. There are a few boosters for when you're properly stuck, but you can get through most levels without them if you're patient.
It plays fine with a mouse, but it's really a one-thumb game. On a phone it's the kind of thing you open in a queue and close three levels later.
