hell of a review! Thanks for playing!
1. Dice Pool, it's arranged in an alternating patter. The highest number in the far left position. The lowest in the middle.
The far right position is the 2nd highest. The position just left of middle is the 3rd highest, and the position to the right of middle is the 4th highest. It's much easier to show than it is to squeeze into a sentence ha!
2. Fill the negativity bubbles 1 at a time, from left to right as they occur. You'll total up your negative points at the end of the game. (So if you fill in 6 bubbles, I believe that's -10 points)
3. For backtracking, you just mark 1 negativity bubble and pick the empty tile for the round.
(And when you mark all your negativity bubbles, you max out)
4. Error Fixing, I think you've got it. 'leftover' would be, after you've filled in a category box (all the 3 dots), you can't fill any more in, so if you have any leftover, you can spend them on error fixing (as many as you want, as long as they match the colors). It's not a rule, i ran out of room, but in general, once you start to fill in a box in a category, you should finish it before doing the error fixing option.
But thanks for the review and the time to write and play! I'll see if there's a way I can rework the instruction to be clearer in this small format.
