Block Logic

About the Game

Block Logic is a calm grid puzzle with two modes. Challenges are 30 hand-verified puzzles: a board of stone blocks and a fixed set of pieces — fill the gaps so every line clears and the board ends empty. Lines clear the moment they're complete, so the order you fill them in matters. Classic is the original endless mode: place three pieces at a time, clear rows and columns, and chase your best score.

How to Play

Select a piece from the tray, then click or tap a cell to place it — pieces can't be rotated. Completing a full row or column clears it. In Challenges, the board starts with grey stone blocks and you get a fixed set of pieces with no refills: fill the gaps so every stone is cleared. A line that completes too early also clears stone a crossing line still needs, so plan the order — if the board can no longer be emptied, the puzzle tells you you're stuck and you can retry. Clearing a puzzle first try earns three stars and unlocks the next. In Classic, you get three pieces at a time, clearing several lines at once scores a combo bonus, and the run ends when none of your pieces fit.

Gameplay Tips

• •Keep at least one open row and one open column free rather than filling the board evenly — a boxed-in grid ends the run even with scattered empty cells left.
• •In Challenges, look for where a row and a column cross: fill the line that shares stone with another line last, or clearing it will wipe blocks you still need.
• •Later challenges include a decoy piece that fits nowhere useful — you don't have to use every piece, only to empty the board.
• •In Classic, check all three tray pieces before placing the first one — an early placement can block the only spot a later piece would have fit.
