Place conveyor-fed blocks and clear rows, columns, and boxes
Tile Fit is a placement puzzle played on a 9×9 board divided into nine outlined 3×3 boxes — the same grid structure as Sudoku, but filled with shaped blocks instead of numbers. Each turn you drag one piece from a tray of three onto the board. When you completely fill any row, column, or 3×3 box, those cells clear and you earn points. After every placement, a new piece enters the tray to keep three available at all times.
The game runs as an infinite survival mode with no time limit. The timer counts up to record your session length, but there is no pressure to rush. The session ends the moment none of the three available pieces can legally fit anywhere on the board. Keeping the board open long enough to keep placing pieces is the primary survival challenge. Building score efficiently while staying alive is the secondary one.
Tile Fit rewards pattern recognition above all — quickly reading how pieces and open spaces interact is the core skill. Logical reasoning governs multi-step planning across the tray. Creative thinking helps you find non-obvious placements that set up large multi-clears. Processing speed matters less here than in the timed games, which is reflected in its lower weight.
Drag any of the three tray pieces onto the board. You can pick pieces from the tray in any order — you are not required to use the leftmost one first. Placement is permanent until cleared. After placing a piece, a new one slides into the tray from the right, always keeping three pieces available. A piece greyed out in the tray cannot fit anywhere on the current board and signals that the board is tightening.
A clear triggers automatically when a row, column, or 3×3 box is completely filled. You can trigger multiple clears with a single piece by filling more than one row, column, or box at the same moment. All qualifying lines and boxes clear simultaneously. Clearing multiple areas at once produces a Multi-clear bonus, which is central to high scoring. The board gives you a preview of what will clear when you hover a piece over a valid position.
If the board reaches a state where none of the three current pieces can fit anywhere, the game ends. This lockout happens gradually through accumulated awkward gaps. Avoiding lockout requires continuously managing open space — particularly reserving room for large pieces, which spawn very frequently.
Scoring: Every piece placed earns 10 points per cell it contains. A 1×1 tile earns 10 points; a five-cell line earns 50 points. These placement points are reliable but modest. The major scoring events are clears. Each clear earns a multi-clear bonus equal to the square of the number of distinct rows, columns, and boxes cleared, multiplied by 100: clearing one line earns 100 points, two lines earns 400, three lines earns 900, and four simultaneous clears — a Quad Clear — earns 1,600 points. All clear bonuses are then multiplied by your current combo multiplier. A Perfect Clear — emptying the entire board in a single placement — adds a flat 1,000-point bonus on top of everything else.

Place conveyor-fed blocks on a 9x9 board. Clear rows, columns, and 3x3 boxes to score — survive as long as possible.
Understand piece distribution. Pieces come from three size categories with fixed probability weights. Small pieces — single cells, dominoes, and small L-shapes — appear only 12% of the time. They are rare lifesavers, not the norm. Medium pieces — straight trominoes, tetrominoes, 2×2 squares, and S- and Z-shapes — are the most common at 48% and form the backbone of most sessions. Large pieces — five-cell lines, large L-shapes, a plus shape, and the 3×3 square — spawn 40% of the time, nearly as often as medium pieces. This means large, space-consuming shapes arrive constantly. You must always maintain open regions capable of accepting them. Treating large pieces as surprises rather than expected deliveries is the leading cause of board lockout.
Build and maintain the combo multiplier. The combo multiplier starts at ×1.0 on your first clear and increases by 0.5 for every consecutive clearing placement: combo 2 is ×1.5, combo 3 is ×2.0, combo 4 is ×2.5, and so on. Critically, the multiplier does not break on the first or second non-clearing placement — you have a buffer of two misses before the third consecutive non-clear resets it to zero. This means you can tactically maneuver over two non-clearing placements without losing your chain, but you must trigger a clear on the third or the streak ends. Keeping your combo alive is worth more over time than chasing any individual multi-clear.
Plan across all three tray pieces, not just the current one. Because you can see and use pieces from the tray in any order, you always have information about the next two placements. A position that looks good for the piece in your hand but blocks the other two from fitting anywhere will cause compounding board problems. Before placing, verify that each of the remaining tray pieces still has at least one valid destination on the board after your move.
Engineer multi-clears deliberately. A single-line clear earns 100 points. A two-line simultaneous clear earns 400 — four times as much for one extra action. Three simultaneous clears earn 900. Look for positions where one piece simultaneously fills a row and completes a column or box. These setups often require building toward multiple nearly-complete lines at once, rather than finishing one at a time. One well-placed piece triggering a triple clear is worth nine single-line clears.
Fill corners and edges before the center. Building from the center outward creates isolated fragments that become impossible to fill when a large piece arrives. Filling corners and edges first keeps the center open for large irregular shapes, and tends to produce clears more naturally as outer rows and columns complete. The 3×3 boxes in the corners are also the easiest to fill intentionally, since they have defined borders on two sides.
Prioritize clearing over arbitrary safe placements. When choosing between placing a piece in a comfortable open spot versus placing it to trigger a clear, the clear is almost always the better choice. Clears free space and build combo. Safe placements accumulate filled cells without return. The endgame pressure is always about space, and only clears create space.
