Tips & strategy
Chase the upper-section bonus early. Filling the number categories generously enough to hit the bonus is worth a large lump of points, and it is far easier to do in the first half of the game while those slots are still open.
Do not waste a good roll on a small category. Three sixes scored in the sixes box is decent, but the same roll in three of a kind may be worth far more depending on the other dice. Check every open slot before committing.
Know when to abandon a chase. If two rolls have not brought you near a straight, take the points that are actually in front of you rather than throwing the third roll away. A modest score beats a zero.
Keep a dump category in reserve. Leaving chance, or a low number slot, open until late gives you somewhere to put a genuinely terrible roll without sacrificing a valuable category.
