Drag, drop and clear the 8×8 grid. Prism Pack is a free block puzzle game. Drag pieces onto an 8×8 grid, clear full rows and columns, chain streaks and match colours for Prism bonuses.
How to play
The board is an 8×8 grid, and the tray below it holds three pieces. Press on a piece and drag it onto the board. It lifts above your finger and a faint preview shows where it will land. Let go to drop it. If the spot is taken or off the board, there’s no preview and the piece glides back to the tray.
Pieces can’t be rotated, so look at every shape before you commit. Once all three pieces are on the board, you get three new ones.
Fill a whole row or column and it clears. Rows and columns clear at the same time, so one well-placed piece can wipe a cross or a corner in one go. While you drag, any lines that would clear light up in the piece’s colour.
The run ends when none of the pieces left in your tray fits anywhere on the board. Pieces that can’t fit right now are dimmed in the tray, so you can see trouble coming.
On a computer you can use the mouse, or the keyboard: press 1, 2 or 3 to pick a piece (Q and E cycle), move it with the arrow keys, and drop it with Space or Enter.
Scoring
- Every cell you place is worth 1 point.
- Clearing lines gives 10 × lines × lines: one line is 10, two at once are 40, three are 90 and four are 160.
- Prism lines: each piece comes in one of five colours. Clear a line where every cell is the same colour and that line’s share of the bonus is doubled.
- Streaks: clear on two drops in a row and the line bonus is multiplied by 2, then 3 for a third, up to ×8. A drop that clears nothing resets the streak. The pill under the score shows the multiplier your next clear will get.
Tips
- Keep space for big shapes. The 3×3 square and the long five-cell lines are the pieces that end runs.
- Play all three in your head first. Placing the easy piece first can leave no room for the awkward one.
- Build toward crossings. A piece that finishes a row and a column together clears both and scores far more than two separate clears.
- Go for colour when it’s cheap. Pieces in the same set often share a colour, so a single-colour row is more reachable than it looks.
How the pieces are dealt
Under about 300 points, the game looks for sets of three that can all be placed, and favours pieces that can finish a line. As your score climbs, awkward shapes become more common and that promise fades. Even then, every new set has at least one piece that fits the board.
Each run lasts a few minutes, and your best score is saved on your device.
