Krillion scoring: the six rarity tiers

Tier	Score	Depth	What it means
One in a Krillion	+100	1,000 m	The rarest valid answer on the board.
Deep Cut	+85	850 m	Obscure but legitimate — specialist knowledge.
Rare	+60	600 m	Clearly correct, clearly uncommon.
Schooler	+30	300 m	A solid textbook answer.
Too Clever	+15	150 m	Technically valid, judged as a stretch.
Plankton	+10	100 m	The most common valid answers.

Use the score calculator or the 700 run builder on today's sheet. Strategy lives in how to get rare answers.
