Learn Mahjong From an Interactable Videotape
At first, this is a fantasy arcade mahjong tutorial.
The tape teaches you how to read tiles, form hands, understand waits, watch discards, and win your first match against a computer opponent.
But after the lesson ends, the tape keeps going.
Real Mahjong, Now Roguelike
You'll quickly transfer your mahjong skills into the roguelike challenge. It is still based on real mahjong rules, but now you can build your tile set, find synergies, win more, and win big.
Build Around Real Mahjong Hands
Every run starts from the language of mahjong: suits, honors, sequences, triplets, pairs, waits, calls, and scoring patterns.
Then the roguelike layer starts bending the lesson.
Add more of the tiles you want. Remove tiles that slow you down. Strengthen certain suits, boost honor tiles, reward triplets, support pairs, or build toward rare patterns. A small change to your inventory can turn a normal hand into the start of something much bigger.
Rewind the Tape
When a round goes wrong, rewind the tape and try another take.
Maybe your opponent wins before you. Maybe your hand wins, but not by enough. Maybe you can already clear the round, but you saw a better hand hiding a few turns back.
Rewinding lets you return to an earlier point in the recording, use what you learned, and play the hand differently. It is not only a safety net. It is part of how you build bigger wins.
