How to play Gate Jam
The board is a grid of coloured blocks, two or three cells long. Around the rim sit coloured gates. Your job is to empty the board: every block must slide out through a gate of its own colour. Blocks never turn corners and never jump over each other, so most of the game is untangling — moving one block out of the way so another can reach its gate.
- Pick a difficulty — Easy, Medium or Hard — then pick a level from the grid and press Play. New levels unlock as you clear the ones before them. Or press the Daily Level button for today’s level.
- Drag a block along its line, or tap it to select it and then tap a cell on its line to slide it there. A horizontal block slides left and right; a vertical block slides up and down. One slide of any length counts as one move.
- When a block has a clear run to a gate of its own colour, drag it straight off the board, or tap its gate’s edge cell, to send it out. It leaves the board for good.
- Undo takes back your last move, free of charge. Reset puts every block back where the level started. Neither touches your score helpers.
- Clear the last block and the level ends. Your moves are compared with par — the shortest solution our solver found — and you earn one to three stars. Match par for all three.
One promise before you start: every level here can be finished. Each board was built by our own level maker and then proven by a solver program, which searched every possible slide and confirmed a full clear exists — and measured the shortest one. If you are stuck, the way out exists; it is just hiding behind the block you least want to move.

Gates, colours and blocking rules
Three rules run the whole game. Learn them and every level is just a traffic problem waiting for the right order.
| Rule | What it means | Example |
|---|---|---|
| A block slides only along its own line | Horizontal blocks move left and right in their row. Vertical blocks move up and down in their column. Nothing turns, nothing moves diagonally. | A red block lying across row 3 can never leave row 3 except through a gate. |
| A block leaves only through its own colour | The gate’s colour must match the block’s colour, and the gate must sit on the block’s row (left or right edge) or column (top or bottom edge). | A blue block in row 3 can use a blue gate on the left or right of row 3 — never a red one, never a gate on another row. |
| The run to the gate must be clear | Every cell between the block and its gate must be empty. One parked block anywhere in the lane closes the exit. | If a green block sits between the blue block and its blue gate, the green block has to move first. |
Two things worth knowing. A gate can serve several blocks of its colour on the same line, one after another. And a block that has left the board never comes back — exits are permanent, and they are always progress, because a gate only ever accepts the colour it was built for.
Scoring, par and stars
Your score rewards fast, tidy solving. Every level starts with a base score and a time bonus that counts down from the moment you start. Wandering moves past par cost a little; hints cost more. Stars only care about your move count.
| Difficulty | Base score | Time bonus |
|---|---|---|
| Easy | 300 points | 2 points per second under 2 minutes 30 seconds |
| Medium | 500 points | 2 points per second under 5 minutes |
| Hard | 800 points | 2 points per second under 6 minutes |
| Daily Level | By its difficulty | Plus a flat 100 point Daily bonus |
Finishing in more moves than par costs 10 points per extra move. Hint (50 points) asks the solver for the best next move: it lights up the block to move, shows where it should go, and tells you how many moves the finish still needs. Stars are simpler: finish in par or under for three stars, within half of par again (at least 3 moves of slack) for two stars, and any finish at all for one. Your best score, your stars, your unlocked levels and your Daily streak all save in your own browser.
7 tips for jam breakers
- Read the gates first. Before your first move, find every gate and note its colour and line. Blocks whose colour has no gate on their line yet are not your problem — they are scenery that other blocks hide behind.
- Free the exit lanes. Most jams are one parked block closing three exits. Look for the block that stands in the most lanes and deal with it first, even if its own gate is far away.
- Park with a purpose. When you move a blocker aside, park it somewhere it closes nothing: an empty row end or a column nobody needs. Thoughtless parking is how easy levels turn hard.
- Long slides are free. One slide of any length is one move. Always slide in full journeys, never cell by cell — shuffling a block three times to cross the board costs three moves where one would do.
- Work backwards from the last exit. Pick the block that will leave last and ask what must be true just before it goes. Planning the end of the level first often untangles the start.
- Undo beats Reset. A jam usually has one wrong turn, not ten. Undo steps back one move at a time and keeps your move count where it was, so back up to the mistake instead of restarting the whole plan.
- Spend hints on Hard, not on pride. A hint costs 50 points but shows a solver-perfect next move and the true distance to the finish. On a Hard level, one good hint early can save twenty wandering moves at 10 points each.

Gate Jam FAQ
Is Gate Jam free to play?
Yes. Gate Jam is 100% free. You play it right on this page in your browser. There is no download, no sign-up and no payment.
How do you play a color block jam game?
Coloured blocks sit on a grid, and each block slides only along its own line — left and right for horizontal blocks, up and down for vertical ones. Coloured gates sit on the edges of the board. A block can leave the board only through a gate of its own colour, on its own row or column, with a clear run to the edge. Clear every block to finish the level.
Does every level really have a solution?
Yes. A solver program checks every level before it joins the bank. It searches every possible slide and confirms the board can be fully cleared, and it records the shortest clearing sequence as the level’s par. Only levels with a proven solution are kept.
What is par, and how do stars work?
Par is the fewest moves any solution needs, measured by the solver. Finish in par or under and you earn three stars. Finish within half of par again (always at least 3 moves of slack) and you earn two stars. Any other finish earns one star. Stars save per level, and new levels unlock as you clear earlier ones.
What does the Hint button do?
Hint costs 50 points and asks the solver for the best next move from the position you are in. It lights up the block you should move, shows its destination, and tells you how many moves the finish still needs from here. You can use it as often as you like — each use costs another 50 points.
Can I play Gate Jam on my phone?
Yes. The game is built for touch: drag blocks along their lines, or tap a block and then tap where it should go. It also works with a mouse and keyboard on laptops and desktop PCs — the arrow keys slide the selected block and Enter sends it out of its gate.
Final verdict: should you play Gate Jam?
Yes — if you like traffic-jam puzzles where one clean plan beats a hundred taps. Gate Jam takes the color block jam game idea and gives it a honest yardstick: every level is solver-proven, par is printed on the level, and the stars tell you exactly how close your plan came to perfect. 24 levels, three difficulties, a daily streak to protect, and no download or account standing in the way. Pick a level and free your first block.
