About this game
Néon Blocks is a block-placement puzzle in the great line of 1010! and Woodoku, built for touch as much as for the mouse. The setting is a candy shop at night: a plum-coloured background and translucent pastel sweets lit from within, each marked with a pattern (stripes, dots, diamonds, a star, a spiral) so that nothing relies on colour alone. The idea is crisp: a square grid of nine cells by nine and, below it, a reserve of three shapes (dominoes, trominoes, T-, S- or L-shaped tetrominoes, squares, long bars of four or five cells…). Nothing falls and there is no timer: you take all the time you want. You pick up a shape from the reserve and drag it with your finger or a mouse onto the grid; a ghost preview, offset above your finger, snaps to the cells, cyan when the placement is valid, a soft red when the shape does not fit. Shapes do not rotate. As soon as a row or a column of nine cells is completely filled, it empties in a burst of light; completing several with a single placement triggers a combo with a generous bonus. When your three shapes are placed, three new ones appear. The game has two ways to play. Classic mode is endless and ranked: the run ends when none of the three shapes fits anywhere any more, and your score is the total of your points (1 per cell placed, plus a growing bonus for rows and columns cleared together). Recipes mode, opened from the Recipes button in the game, offers 20 orders from the candy shop spread over five shelves of four: each recipe has a goal (clear a number of lines, free candies trapped inside the sweets, or reach a score), a limited number of pieces and often a starting grid that is already filled in. You lose it when you run out of room or of pieces, and it earns 1 to 3 stars depending on how many pieces you save. Clearing a recipe unlocks the next. Recipes are outside the leaderboard. Create an account to sync your Classic records, enter the leaderboard and unlock trophies, including ones for the recipes you clear. Néon Blocks is free in your browser, nothing to install, on desktop and mobile alike.

How to play
Place shapes on a 9×9 grid and complete whole rows or columns to clear them: score as much as you can in Classic mode, or clear the goal of all 20 recipes using as few pieces as possible.
Game rules
- You have a 9×9 grid and a reserve of three shapes (polyominoes): dominoes, trominoes, squares, bars, T-, S- or L-shaped tetrominoes. They do not rotate.
- Nothing falls and there is no timer: you take all the time you want to think about the best placement.
- Drag a shape onto the grid: a ghost preview, offset above your finger, shows in cyan when the placement is valid and in a soft red when the shape does not fit.
- A shape can only be placed on cells that are completely free, without overlapping a block that is already there.
- As soon as a row or a column of 9 cells is completely filled, it empties at once and scores points; emptying several with a single placement triggers a combo.
- When your three shapes are placed, three new ones appear. In Classic mode, the game goes on as long as at least one shape can be placed.
- Recipes mode: the Recipes button in the game opens the map of 20 recipes, laid out on five shelves of four. Each has a goal (clear a number of lines, free candies trapped inside the sweets of the starting grid, or reach a score), a limited number of pieces and often a starting grid that is already filled in. The first is open; each next one unlocks as soon as the previous one is cleared.
- A cleared recipe earns 1 star, 2 or 3 if you save enough pieces (the ones you did not need to place). It is lost if the grid has no room left for your shapes or if you run out of pieces before the goal: you can replay it.

How a run ends
In Classic mode there is no final win: you play for the score, and the game ends when none of the three shapes in the reserve can be placed anywhere on the grid. In Recipes mode you win by filling the goal within the piece limit, with 1 to 3 stars depending on the pieces you save, and you lose if there is no room or no piece left. Only Classic mode counts for the leaderboard; recipes earn stars and trophies, and your progress is saved on your device.
Tips & strategy
Keep free space
Do not fill the grid at random. Always leave open areas able to take the big shapes such as the 3×3 square or the five-cell bars, or you will soon find yourself stuck.
Go for combos
Completing several rows or columns with one placement triggers a combo with a generous bonus. Prepare a hinge cell that will close two lines at once to maximise your points.
Plan for all three shapes
Look at your three pieces before you place the first. Place them in the order that preserves the most options, saving bulky shapes for the spaces that suit them.
In a recipe, count your pieces
Every piece you place counts against your budget. Look for the placement that moves the goal forward fastest: the sooner you finish, the more pieces you save, and the more stars you earn.
Did you know?
Block placement without gravity descends from the puzzle “1010!”, released in 2014, which took the idea of a board to fill with pieces placed freely rather than falling from the top as in Tetris. The idea exploded on mobile thanks to its instant pick-up-and-play feel.
The 9×9 grid variant was popularised by “Woodoku” and its cousins, which marry sudoku logic (rows and columns to complete) with the handling of polyominoes. It is that cross between considered filling and the satisfaction of an instant clean-up that makes the genre so addictive.
Frequently asked questions
- Is Néon Blocks free to play?
- Yes. Néon Blocks is completely free and runs straight in your browser — no download, no install, no paywall.
- How do you play Néon Blocks?
- Hit “Play” to start Néon Blocks. It runs on keyboard on desktop and on touch controls on phones and tablets — no controller needed.
- Do I need an account to play?
- No — you can play right away as a guest, and your best score is kept on this device. A free account (by email link, no password) syncs your high scores, puts you on the leaderboards and unlocks trophies.
- Does Néon Blocks work on mobile?
- Yes. The game is responsive and fully playable with your fingers on phones and tablets, just like on desktop, with no app to install.
- Can I rotate the shapes before placing them?
- No, pieces are placed as they are, with no rotation. The whole strategy is precisely to find the right spot for each shape in its original orientation, which pushes you to plan ahead rather than improvise.
- What happens if I complete a row and a column at the same time?
- Both empty simultaneously and you trigger a combo. The cell where they cross is only counted once, but the combo bonus clearly rewards this double clean-up done with a single placement.
- What is Recipes mode?
- It is 20 challenges with a precise goal (clear lines, free trapped candies or reach a score) and a limited number of pieces, played by the same rules as Classic mode. Clearing a recipe earns 1 to 3 stars and unlocks the next. They are outside the leaderboard.
- Are my cleared recipes saved?
- Yes, on your device: the map remembers the recipes you have opened and your stars. It is not synced between devices; recipe trophies, however, unlock on your account when you are signed in.
