In Copyright, players need to reproduce a pattern as quickly as possible using the transparent image sheets that they have in hand. Each sheet is a 3x3 grid that has a circle, a square, and a plus in three of its nine squares.

At the start of a round, one player takes four image sheets at random, then stacks them together to form a model for that round. Players receive ten sheets at random, then try to reproduce the model by flipping the sheets and stacking them any way they like; the sheets do not have to overlap perfectly, but a player will lose points for any non-perfect overlaps. How does a player indicate which squares in his stack are to be considered the solution? Through the use of a 3x3 grid that has a thick black outline; each player has one of these in addition to the ten sheets.

As soon as a player recreates the model, the round ends. Each player scores one point for each square in the model that she reproduced in her image; whoever ended the round receives one bonus point, scoring 10 points (instead of nine). All players then lose one point for each row and column that "sticks out" from her 3x3 black-bordered grid. Players then shuffle the sheets and start a new round.

When a player’s score totals 20 or more points, the game ends and this player wins.
