The trump suit plays the most pivotal role in the game of euchre. When a suit is named trump, any card of that suit outranks any card of a non-trump suit. The highest ranking card in euchre is the Jack of the selected suit, referred to as the Right Bower. The second highest card in euchre is the other Jack of the same color, referred to as the Left Bower. If spades where trump the Left Bower should be treated as a spade throughout the hand. The remaining cards of the trump suit rank A, K, Q, 10, and 9. The other three off-suits rank A, K, Q, J, 10, 9. Please note, if the jack is the Left Bower, it is considered part of the trump suit. Thus, it is not a part of the off-suit. The table below shows the rank of the cards from highest to lowest if that suit is called trump.
