How to Play Block Puzzle

Your goal is to keep placing pieces and clearing lines for as long as you can.

1. Choose a piece from the tray. You can use the three available pieces in any order.
2. Find a space on the board. Every square of the piece must fit inside the 8×8 grid without overlapping an occupied square. Pieces stay in the orientation shown; they cannot rotate.
3. Complete a row or column. Filling every square in a horizontal row or vertical column clears that line. If one placement completes several lines, they clear together.
4. Use all three pieces. A fresh set appears after you have placed every piece in the current tray.
5. Keep space for another move. The run ends when none of the remaining tray pieces fits anywhere on the board.

Controls: Drag, Tap or Use Your Keyboard

Mouse or touch: Drag a piece from the tray onto the board. You can also select a piece first, then tap or click the board to choose its top-left position.

Keyboard: Tab to the board or a tray piece first. Press 1, 2 or 3 to select a tray piece. Use the arrow keys to move its placement position, then press Enter to place it.

Read the Shape Before Choosing Its Position

A piece’s width and height help you check whether it can fit near an edge. Count the columns and rows it spans in the orientation shown. Every filled square in that shape needs an empty destination on the board.

For example, a piece that spans three columns cannot begin in column 7 of an eight-column board: part of it would extend past the right edge. Starting in column 6 keeps its width inside the board, but you still need to check for occupied squares under the shape.

This check is especially useful with tap placement. The square you tap selects the piece’s top-left position, so choose that starting point with the whole shape in mind.

How Scoring Works

You earn 1 point for each small square in a piece you place, plus 10 points for each complete row or column you clear.

For example, placing a piece that covers three squares earns 3 points. If that move also completes one row and one column, the two cleared lines add 20 points. That makes 23 points for the move.

A row and column completed together each count as a cleared line. Look for opportunities to clear more space while keeping the remaining pieces playable.

Three Ways to Plan Your Next Move

Look at the Whole Tray

Before placing the easiest piece, check the other two. One may have several possible positions while another fits in only a small part of the board. Consider using that restricted space first. Thinking through the order of all three pieces can prevent an early placement from blocking a move you still need.

Keep Useful Spaces Open

Empty squares are most helpful when they form spaces that a piece can actually use. Scattered single-square gaps can leave the board looking open while offering few valid moves. When two placements seem equally good, compare the spaces they leave behind. Connected open areas generally give you more ways to accommodate the rest of your tray.

Check the Move After a Clear

Completing a row and column together earns two line bonuses and frees space in both directions. Before building toward that move, check whether your other pieces will still fit. A smaller clear can be a better choice if it keeps your run going. Consider both the points you earn now and the room you leave for the next placement.

Work Through a Placement Before You Make It

Plan the Order of Your Three Pieces

Your current tray is a small planning problem. Start by checking where each piece can go, then consider how one placement would change the choices for the others. The board will not necessarily stay the same while you use the tray: clearing a line may create a position that was unavailable before.

For example, a small piece might complete a nearly full row. Removing that row could make room for a wider piece. Identify that sequence before filling the same area with another piece. After the third piece is placed, reassess the board using the new tray.

Check the Board Before and After a Clear

Before placing a piece, run through this short check:

1. Check its footprint. Make sure every square of the piece fits inside the board and avoids occupied squares.
2. Identify complete lines. Look across the affected rows and down the affected columns. Only fully filled lines will clear.
3. Review the resulting space. Imagine those completed lines removed, then check where your remaining tray pieces could go.

A placement can score points while still leaving an awkward board. Compare the next available moves as well as the immediate clear. You have time to do this because there is no countdown.

When comparing two possible placements, keep the awkward remaining piece in mind. If it fits only in one corner, using that corner for a different piece may remove your last option. A move that preserves this position can be more useful than a convenient placement elsewhere, even when both earn the same immediate score.

Try Tap Placement on Smaller Screens

If dragging makes it difficult to see the destination on a smaller screen, try tap placement. Select the piece in the tray first, then tap the board at the intended top-left position.

Before that second tap, compare the displayed shape with the available space. Count how far it extends across and down, especially near the right or bottom edge. This gives you a deliberate two-step way to choose a piece and its position without needing a continuous drag.

Why Empty Squares May Not Be Enough

The number of empty squares does not determine whether a move exists. Their arrangement matters. Imagine a board with six empty squares, each separated from the others by occupied squares. If every remaining piece needs at least two adjacent squares, none will fit.

The game can therefore end with visible gaps. Check the pieces still in your tray against the spaces actually available. A hypothetical piece from a future tray cannot keep the current run going.

Frequently Asked Questions

Is There a Time Limit?

No. This version has no countdown. You can take time to compare placements before making a move.

Can I Rotate the Pieces?

No. Each piece must be placed in the orientation shown in the tray. Check its shape against the available spaces before placing it.

Why Have No New Pieces Appeared?

The tray refills after you place all three pieces from the current set. Clearing a line by itself does not replace the pieces still in your tray.

Why Did the Game End When the Board Still Had Empty Squares?

At least one remaining piece must fit completely into an available space. Empty squares alone are not enough if their arrangement does not match any of the pieces you have left.

How Do I Keep My Progress?

To resume a saved run, return to the same site address in the same browser. Your current game and best score depend on that browser’s saved site data. Another browser or device will not automatically have that save.

A different domain also has separate site storage. If you open the game at a new website address, your earlier save may not be available. Do not assume progress will move with you unless a transfer option is explicitly provided. Clearing the original site’s stored data removes the save held there.
