noun
not fishing; needing more than one tile to win
Mahjong term: a hand that is not in tenpai (ready to win) and needs at least one more tile to reach a winning shape. Contrasts with テンパイ (tenpai).
See also: テンパイ
この手はまだノーテンだから、もう一枚必要だ。
This hand is still noten, so I need one more tile.
ノーテンで流局した。
The round ended with me not in tenpai.
テンパイ (tenpai) means the hand is one tile away from winning; ノーテン is the opposite state, needing more than one tile.
From English 'no' + 'ten' (short for tenpai), a mahjong term. The kanji 不聴 is a direct translation of the meaning, but the katakana form is standard.
