Rulesets Taught and Practiced on tsumo
tsumo is not a generic single-ruleset Mahjong clone. The site keeps separate teaching paths, validation rules, puzzle surfaces, and playable browser modes for six rulesets so a player can see exactly which rule caused a win, claim, or scoring decision to succeed or fail.
Simplified Chinese Mahjong
Best first ruleset for learning the basic draw, discard, call, and 4 sets plus 1 pair hand shape without a heavy value gate.
Hong Kong Classic Mahjong
Adds flowers and a 3 non-flower faan requirement, so players learn why complete shape and scoring value are separate checks.
Riichi Mahjong
Focuses on yaku, dora, furiten, riichi timing, and defense, making it the most tactical ruleset for push-fold practice.
MCR Mahjong
Uses pattern combinations and an 8 non-flower point gate, which rewards planning a main scoring route and a backup route.
Filipino Mahjong
Uses 16-tile hands, flower-replaced honors, Secret Kong side payments, and Todas or Bunot multiplier payouts.
Taiwanese Mahjong
Uses 16-tile flow, meldable honors, additive tai scoring, and a 1 tai minimum after the winning draw or claim.
How to Use the Tutorial Library
Choose one ruleset and use its tutorial as a hands-on lesson rather than a checklist to finish quickly. Simplified Chinese is the clearest starting point when drawing, discarding, forming melds, and recognizing a complete hand are still new. The mode summaries above show the hand structure and value focus to expect before a lesson begins.
Pause whenever a tutorial presents a claim or winning decision and explain why the move is legal in that mode. The draw-and-discard rhythm transfers across Mahjong variants, but scoring gates do not: Hong Kong play checks non-flower faan, Riichi requires a yaku, MCR requires enough pattern points, and the Filipino and Taiwanese 16-tile modes treat honors and bonus tiles differently.
After one tutorial, play a bot game in the same ruleset and focus on one skill such as legal claims, hand shape, or value. Return to the linked rules guide only when you can name the decision that caused trouble. This tutorial-to-rules-to-practice loop keeps details from several variants from blending together.
