20 themed districts
Roundabouts & train crossings
Easy to read, tricky to master
One rule: cars go where their arrow points. Hundreds of crowded boards turn that rule into a brain-tickling puzzle.
Tap. Flow. Unjam the city.
The city is stuck and only you can get it moving. Read the arrows, tap the free cars in the right order and watch a crowded traffic jam melt away. Then do it again across 1000 levels.

Mini Jam
Flow ×0
Tap a car to send it along its arrow. If something is in the way it bumps and you lose a heart. Clear all 11 cars!
The game
A whole toy city, stuck in traffic.
Taxis, buses, ice-cream trucks and a very busy fire engine, all wedged bumper to bumper. You're the one with the plan.
What is JamSolve?
JamSolve is a casual traffic jam puzzle game for iPhone and Android by Marvo Games. Every car shows an arrow. Tap a car and it drives along its route, as long as the road is clear. Find the right order, keep the cars flowing and clear crowded city boards of 20 to 60 vehicles.
Officer Pug approves
Pure, satisfying flow
Clean exits chain into Flow, Flow ignites Fever, and the last cars zoom off in a Rush finale.
Something new every win
Fill the garage meter for free cars, open chests, spin the coin multiplier and unlock a new district every 50 levels.
How to play
Three taps to traffic zen.
No tutorials to sit through. You'll get it in five seconds and still be thinking about level 400 on the bus.
-
1
Read the arrows
Each car's arrow says where it will drive: straight, left, right or a U-turn at the next junction.
-
2
Tap the free car
If its road is clear it zooms off the board. Tap a blocked one and it bumps: three bumps and the level is over.
-
3
Keep the flow
Chain clean exits for Flow tiers: Good, Great, Perfect. Clear the board with the fewest bumps to earn three stars.
Street smarts
The city keeps surprising you.
New road rules arrive district by district, so the puzzles never settle into routine.
Crosswalks
Walkers have right of way. Time your tap so nobody gets honked at.
Traffic lights
Go on green, never on red. Lights cycle, so watch the rhythm.
Roundabouts
Cars circle the island and take their exit: right is first, straight is second, left is third.
Railway crossings
Bells ring, barriers drop, a train thunders past. Cross only when the barrier is up.
Buses & trucks
Two cells long and twice as stubborn. Clear their path before they block everyone else.
U-turns
Some cars loop back at the next junction. Plan two moves ahead.
Combos
Ten clean exits. Fever!
JamSolve rewards rhythm. String exits together without a single bump and the whole city speeds up.
Flow Fever
Every 10 clean exits in a row trigger 6 seconds of Fever: cars move faster and every exit pays a bonus coin.

Rush finale
When only free cars are left, nobody waits. Everything drives off at once in a Rush finale, and you just enjoy the show.

Coin multiplier
A needle sweeps across ×2, ×3 and ×5. Stop it at the right moment to multiply your level coins.
Free gift chest
A gift waits on the home screen and refills every few hours. Coins, sometimes a booster, always a little smile.

Win streaks & hard levels

FAQ
Questions, answered.
What is JamSolve?
JamSolve is a casual traffic jam puzzle game for iPhone and Android by Marvo Games. Each car carries an arrow that shows where it will drive. You tap cars in the right order so every one leaves the crowded city board without crashing.
How do you play JamSolve?
Read the arrow on a car, check that its route is clear, and tap it. Free cars drive off the board; a blocked car bumps and costs a heart. Clear every car to win the level. Chaining clean exits builds Flow and, at ten in a row, Flow Fever.
How many levels does JamSolve have?
JamSolve contains 1000 levels spread across 20 themed city districts, from cherry-blossom streets to a snowy town and a royal city. New mechanics such as crosswalks, traffic lights, roundabouts and railway crossings are introduced along the way.
Is there a timer?
No. Levels have no countdown timer. You have three hearts per level, and retrying a level is always free.
Which languages does JamSolve support?
JamSolve is available in English, Turkish, German, Spanish, French and Arabic.
