17 Steps is a fast-paced, highly strategic mahjong duel inspired by the classic Japanese mahjong variant “Juu Nana Ho” — Seventeen Steps.There is no slow hand-building here. From the very beginning, both players are already one step away from victory.The real battle begins after the hands are locked.<h2 class="bb_tag" >A Duel Decided in 17 Moves</h2>At the start of each round, both players receive 34 tiles. From these, you choose 13 tiles to form a ready hand. The remaining 21 tiles become your discard candidates for the duel.Your initial choice shapes the entire round.Do you aim for a higher-value hand? Do you choose a hidden wait that is harder to read? Or do you leave yourself safer options for defense?Once both players confirm their hands, the 17-step duel begins.<h2 class="bb_tag" >No Tsumo. Ron Only.</h2>During the duel, there is no drawing and no self-draw win. Players take turns discarding one tile from their candidate discard pool.There is only one way to win:Make your opponent discard the tile you are waiting for.If you discard your opponent’s winning tile, they win. If your opponent discards your winning tile, you win.If no one wins within 17 moves, the round ends in a draw.<h2 class="bb_tag" >Pure Defensive Mind Games</h2>No chi. No pon. No kan. No tsumo.Only the sharpest parts of mahjong remain:Reading, hiding, baiting, and surviving.Every discard is a risk. Every safe-looking tile might be a trap. You must read your opponent’s possible waits while hiding your own.In 17 Steps, victory is not about drawing the perfect tile. It is about making your opponent make the wrong move.<h2 class="bb_tag" >Han Requirement and Comebacks</h2>To win the round, your hand must reach 4 han or more after scoring.If your hand is below 4 han, even a successful ron will result in a draw. However, after a winning hand, an ura-dora indicator is revealed. If your winning hand contains the matching tile, each copy adds 1 extra han.This means even a hand that starts below the requirement may still turn the game around at the final moment.<h2 class="bb_tag" >Classic Japanese Mahjong Yaku</h2>The game includes a variety of classic Japanese mahjong yaku, such as:Riichi, Menzen Tsumo-related scoring elements adapted for this rule set, Pinfu, Tanyao, Chiitoitsu, Yakuhai, Honitsu, Chinitsu, as well as yakuman hands such as Kokushi Musou, Suu Ankou, and Daisangen.Dora, red dora, and ura-dora are also included, bringing explosive comeback potential to each short match.<h2 class="bb_tag" >Game Modes</h2>Practice against AI opponents and sharpen your reading, defense, and discard judgment.Or invite a Steam friend and jump straight into a quick duel.Whether you want a short match or repeated strategic practice, 17 Steps is designed for fast, intense play.<h2 class="bb_tag" >Language Support</h2>Simplified Chinese / Traditional Chinese / English / Japanese / Korean / Spanish / Russian<h2 class="bb_tag" >Inspiration</h2>17 Steps pays tribute to the iconic “Seventeen Steps” mahjong duel from Tobaku Datenroku Kaiji.Under extreme pressure and limited turns, every discard matters.
