how does the ratings work on the cribbage games?

Answer 1

Scoring During Play
Instructions
STEP 1: Peg two and say "fifteen two" if you play a card that brings the total to 15. STEP 2: Peg two if you play cards that bring the total to 31. STEP 3: Peg two for a pair if you play a card that is the same rank as the preceding card. STEP 4: Peg six for a pair royal if you play a third card that is the same rank as the preceding two cards. STEP 5: Peg 12 for a pair royal if you play a fourth card that is the same rank as the preceding three cards. STEP 6: Score for a run if you play the last card in the run. Tips & Warnings
Runs don't have to be played in order if no other cards intervene. For example, 2, 3, 5, 4 and 6 is a run. The 3 scores two, and the 6 scores five.
Ace is always low, so the sequence must go ace, 3, 2, etc. for the ace to be part of a run.
