James Dwight,
The Laws of Euchre
“ Should a player order up, assist, adopt, or make the trump, and he and his partner take five tricks, they score two; three or four tricks, they score one. If they fail to take three tricks they are euchred, and the adversaries score two.3. When a player plays alone and takes five tricks, he scores four; three or four tricks, he scores one. If he fails to take three tricks he is euchred, and the adversaries score four.4. The penalty of a revoke takes precedence of all other scores.5. An error in the score can be rectified at any time before the trump card is turned in the next deal. ”
