Object: Cover the given pattern with 15 of the 16 given Tetrasticks.
 
You have 16 tiles ('Tetrasticks') available with are made from 4 straight segments each. Click one of the small images of the tiles at the top left to select a tile. Click again to rotate and flip (mirror) it until it is presented the way you want to place it. Now click one of the black grid points on the playing board on the right to place a tile.
 
You have to use each tile exactly once. Tiles are allowed to cross each other.
 
The 'sweet spot' of a tile is always on the left side of the lowest part. It is indicated by a red dot.
 
Variant 1: Fill the given green square with 15 of the 16 given Tetrasticks without gaps or overlaps. (There are five tiles that can be omitted from the solution; which are they?)
Variant 2: Fill the given green figure with 15 of the 16 given Tetrasticks without gaps or overlaps. (There are two tiles that can be omitted from the solution; which are they?) Once you have succeeded in doing this, try to find solutions which do not have any tiles that cross each other (for both variant 1 and 2).
Variant 3: Free Play; uses the whole big board.
Variant 4: Free Play; you may use each tile more than once.
 
Please note that there are two piece sets available.
 
The Tetrasticks have official names which are letters from the alphabet. They are called I, C, F, H, J, L, N, O, P, T, U, V, W, X, Y, Z. (reading from left to right and from top to bottom of the playing board).
