I appreciate you taking the time to read my game, but I really recommend you check out the game page. As detailed there, this game is also an entry to "Minimalist TTRPG Jam" which encouraged specifically the use of the most basic of layouts possible (I entered it into "Lesser Loved Dice TTRPG Jam" as well because the jam periods overlapped nicely and this jam specifically encouraged entering games that were not created for this jam alone). The page xxx thing is on me, a thing I missed and will correct. I've already corrected it.
2d10 and 1d100 is used interchangably because a lot of people use 2d10 as a d100. It doesn't matter if it's two dice or one because the system still works. The lines you draw simply divide your paper in four parts which make the mechanic possible. Both top parts indicate up, both left parts indicate left, both bottom parts indicate down and both right parts indicate right. Compare:
Dice | d100 | 2d10 |
Dice location after roll | lower right corner - 32 | One dice (the one for the tens place) in lower right corner - 30, the other (the one for the ones place) in the upper left - 2 |
Meaning | Down 3 spaces, to the right 2 spaces | Down 3 spaces, to the left 2 spaces |
