Things that one must keep in mind during Blokus play:
* Smaller tiles are useful during the later stages of the game: the smaller a piece is, the better it is at occupying holes between the tiles of other colors.
* It is usually advisable to use up the 5-square tiles early on, because they are difficult to place as the board fills up and have the greatest impact on one's final score.
* Typically, games begin with players moving quickly toward the board's centre using the larger pieces (Z5, W5, F5, L5, N5, T5, X5, and V5), and attempting to establish as many usable corners as possible.
* When placing pieces next to an opponent's pieces, there are three possibilities: to "hang" (block off one of their corners, but thus leaving your own corner exposed to retaliation), "kiss" (exactly meet at the corners, which provides guaranteed passage for yourself but also for your opponent) or "short" (fall short of the space you wish to move to next turn; this only works if your opponent cannot block the next move).
* Establishing "eyes" (small hemmed-in spaces of one, two or three cells) is important: other players cannot move into them without wasting valuable small tiles.
* "Jagged" spaces with lots of corners are more defensible (because they can be easily turned into eyes) than rectangular spaces, which allow opponents to hug the walls and lay down larger pieces.
* Pieces with long sides (3, 4 or 5 squares) must be deployed carefully, as the sides both block your own future moves and offer opponents safe passage.
