If you know it as mahjong connect, this mahjong tile puzzle adds a race: two players share 80 tiles, and whoever links a pair first takes it. An energy bar drains instead of a clock and a wrong pick costs a chunk, so calm, certain pairs win. Learn the shisen sho rules against AI for free, then sign in to face people.
In GameNow's Shisen-Sho a match is a race on a single board. Both players clear the same 80 tiles at once, each pair goes to whoever connects it first, and the pairs your opponent takes disappear from your screen behind a dashed line. Their selected tile is outlined on your board as they pick it, so you can see which pair they are going for before they finish it.
Instead of a clock, each player has an energy bar. It drains 0.55% per second, emptying in about three minutes if untouched; a pair adds 0.8%, or 1.2% within three seconds of your previous one, a miss takes 4% and a hint 10%. In a match energy breaks ties; in the daily challenge it is the time limit.
Boards are generated from a seed and played through before anyone sees them: the generator removes random open pairs, and if six such runs all get stuck it deals a new board. The same seed always gives the same board, which is how both players in a match, and everyone on the same day's challenge, get an identical layout.

How to play
- Pick Easy, Normal or Hard and an AI shares the board with you. Signed out, choosing a level in the box at the top starts a new board at once; signed in, pick it under Solo play in the lobby and press Start practice. After a game, Enter plays again and Esc leaves. To play a person, press Find opponent.
- Press a tile to select it, then press a matching tile; if they connect, both are removed. Pressing a different tile just changes your selection.
- The connecting line may pass only through empty cells (the outer border counts) and bend at most twice, so edge tiles open up first.
- Tiles your opponent selects get an orange outline. Whoever connects a pair first takes it.
- Energy drains over time and refills when you remove pairs. Misses and hints cost energy; at zero you stop.
Modes
- Solo play (Easy · Normal · Hard)
- An AI shares the board with you. On average it takes a pair every 5.2, 3.5 or 2.3 seconds, and it deliberately picks an unconnectable pair up to 8%, 4% or 1.5% of the time. On Easy, selecting a tile also outlines the other tiles of that pattern.
- Find opponent
- Two signed-in players share one board held on the server. It ends when the board empties, both are out of energy, the remaining pairs can no longer change the result, or after 6 minutes.
- Today's Shisen-Sho
- Signed-in players clear one daily board alone. It changes at midnight Korean time (15:00 UTC); the score is pairs × 1,000 plus energy left on a 1,000-point bar (up to 999), and only your best attempt of the day is kept.
- Watching
- Live matches can be opened from the lobby. You see both players' selections, lines and energy bars, but cannot touch the board.
Good to know
- A miss costs as much energy as five pairs earn. Take the sure pairs first.
- If no pair can be removed, the remaining tiles shuffle automatically, with no penalty.
- Today's Shisen-Sho gives everyone the same board to clear alone, ranked by pairs and energy left. You can watch live matches from the lobby.
