Bus Jam is a 3D parking puzzle: a lot packed with buses, a ring of colour-coded passengers going round it, and four bays in between. Every bus points somewhere, and tapping one sends it straight ahead — so the whole game is working out which bus can leave now, and whether it is the colour the queue actually needs.
The lot is the puzzle. Buses sit at every angle, nose to tail, and a bus can only drive in the direction it is already facing — tap one with something in front of it and it shakes and stays where it is. So the first question is always which vehicles are free to move at all, and the second is whether moving them opens or buries the one you really want.
The second question is the one that decides levels, because the passengers are picky. Around the lot a ring turns with rows of colour-coded people on it, and they board only a bus of their own colour. There are four parking bays to start with, and once a bus is parked it is committed: it sits there taking its colour until it is full and drives off. Fill your bays with the wrong colours and the ring keeps turning with nobody able to get on.
That is the deadlock the title warns about. If the ring is full, none of the parked buses match anything on it, and there is no free bay left, the level is over and you start it again. Three more bays can be unlocked with the coins you earn — seven in total — and they are the pressure valve, but the coins are finite and the price rises with each one, so an extra bay is a decision rather than a habit.
Buses differ in size: small ones take four or eight passengers, long ones eight, twelve or sixteen, and a full bus pulls away, frees its bay and pays out — five coins for a big one, three for a medium, one for a small. From level 20 the lot also refills, with fresh buses rolling in from off-screen as the pile thins out, so clearing the visible cars is not the same as clearing the level.
There are 300 levels and they build slowly: the lot grows from four columns to nine, the rows from four to thirteen, and the palette from two colours upward. Every level is generated from its own number, which means level 137 is the same level on your phone as on your laptop, and every layout is checked to be solvable before you ever see it — if you are stuck, the order is wrong, not the level.
How to play Bus Jam
One tap does everything. The thinking is in the order:
- Tap a bus to send it out of the lot. It drives straight ahead, so it can only leave if its path is clear.
- A bus that gets out parks in one of your bays. You start with four.
- People on the ring board the bus that matches their colour; a full bus drives off and frees its bay.
- Coins come from departing buses — 5 for a big one, 3 for a medium, 1 for a small.
- Spend coins to unlock extra bays, up to seven, or watch an ad for one.
- If the ring fills up, no parked bus matches it and no bay is free, it is a deadlock and the level restarts.
Game modes
| Mode | What changes | Who it's for |
|---|---|---|
| Campaign | 300 hand-tuned-by-number levels: the lot widens from 4x4 to 9x13, colours multiply, and from level 20 a second wave of buses arrives from off-screen as the pile thins. | Everyone — it is the whole game, and cleared levels stay ticked in the level list. |
| VIP levels | From level 25, every fifth level hides one black VIP bus deep in the pile and adds a bay of its own. When the VIP passenger reaches the ring a patience timer starts — about a minute early on, tighter later — and if it runs out the level is lost. | Players who want a clock on top of the puzzle; they arrive on their own as you progress. |
Tips for Bus Jam
- Read the noses before you tap anything. A bus is free only if the lane it is facing is empty all the way out, so the pile has an order and most of it is not the order you see first.
- A parked bus is a committed bay. Sending out a colour nobody on the ring wants costs you a quarter of your parking for as long as it sits there.
- Watch what is coming round the ring, not just what is in front of it. The colour you can serve in ten seconds matters more than the one you can serve now.
- Big buses pay five coins and small ones pay one, but big buses also hold a colour far longer. Late in a level the small one is often the better clear.
- Save coins for the fourth and fifth bay rather than buying the first extra bay early — the price climbs with every bay you open.
- On VIP levels find the black bus first and count how much digging it needs. The timer only starts when the VIP reaches the ring, so the work you do before that is free.

About this game
- Controls
- Tap or click a bus to send it out of the lot. A bus only ever drives straight ahead, so it leaves only if nothing blocks the way it is facing — a blocked bus shakes and stays put. Buses that get out take a parking bay next to the ring, and passengers of the matching colour board them.

Frequently asked questions
Is Bus Jam free to play?
Yes. It runs free in your browser on crokocat with no download and no sign-up, on desktop, phone and tablet.
How do you play Bus Jam?
Tap a bus to send it out of the lot. Buses only drive straight ahead, so one can leave only if nothing blocks the direction it faces. A bus that gets out parks in a bay, passengers of the matching colour board it, and when it is full it drives off and frees the bay.
What happens when I get a deadlock?
A deadlock is called when the ring is full, none of the buses in your bays match a colour on it, and there is no free bay left to park a bus that would. The level ends and you can try it again from the start — the layout is identical, so it is a puzzle to re-solve rather than a new deal.
How many parking bays can I have?
Four to start with and seven at most. The extra three are unlocked one at a time with the coins buses pay when they depart, or by watching an ad, and each one costs more than the last.
How many levels does Bus Jam have?
300. Each is generated from its own level number, so the same number is the same layout on every device, and each one is checked to be solvable before it appears.
What are the black VIP buses?
From level 25 onward, every fifth level hides a single black VIP bus deep in the lot and opens a dedicated VIP bay. Once the VIP passenger reaches the ring a patience timer runs — roughly a minute at level 25 and shorter as the levels go on — and if it expires the VIP gives up and the level is lost.
Does Bus Jam save my progress?
Yes. The highest level you reached and your coin balance are stored on your device, and cleared levels stay ticked in the level list so you can go back to any of them.
