Abstract played on a board of 5 x 5 squares. Each player has thick, wooden tiles that cover 1, 2 or 3 linear squares plus three neutral tiles. The tiles score 1, 5 or 10 points respectively, with the neutrals worth zero.
Like Domain, Cathedral and others, players alternate to fill up the lowest "level" of the game board. The last player to play on the first level starts level 2, the same goes for level 3. Upper level tiles can only be played covering the player's color or neutral tiles.
Levels are scored as they are completed, with a multiplier of the level number (1,2,3).
The original game came with game board (signed and numbered by the author), rules, a scorepad and golf pencil, plus the following tile distributions.
Player sets (blue and white) each have
15 "ones" (one square)
5 "fives" (2 squares)
3 "tens" (3 squares)
7 Neutral red tiles (one square)
