This is a simple Martian Dice score sheet (not as cool as Topher Pierce's very clever player aid!).

Each line has 25 dots you ink in for each score. The first line is for the player's initials; the last line is for the final score (because score can go higher than 25).

Print double-sided and cut out the sheets. They'll fit in the tube. Each cut-out let's you track 8 scores on each side.
