How it works

Sign up free. Type your name and email above, and I'll email you a 6-digit code to confirm it's you. It takes about a minute.
Play one tournament game a day for 5 days, Monday to Friday. Each game is a full game of American Mahjong against three computer players.
Your points add up all week. The player with the most points at the end wins the prize.

Play anytime you want

You never have to show up at a certain time. Each day's tournament game is ready at midnight and stays open until the next midnight, on your own clock. Play with your morning coffee, on your lunch break, or after the kids are in bed. It all counts the same.

Miss a day? You're still in. That day just adds no points to your score, and you can jump back in the next day.

Signing up late is fine too. Sign-up stays open all tournament week, so you can join on any of the 5 days and play the days that are left.

The prize

The top score wins a prize, shipped right to your door.

I announce the winner the Saturday after the tournament ends, and I email the winner that day.
Prizes ship to US addresses only.
The winner has 7 days to send me a shipping address, or the prize goes to the runner-up.

The rules

No hints and no blanks. The coach is turned off, so every decision is yours.
Everyone plays the same game. Each day's tiles are dealt the same for every player, against Intermediate computer players.
Your first game each day is the one that counts. Once the tiles are dealt, that's your game. If you leave or start over before it's finished, that day scores 0 points. You can play it again afterward, just for practice.
One entry per person. If you play on more than one phone or computer, sign up on each one with the same email and your points go to the same score.
Play your own game. Please make your own decisions and don't share the day's tiles before others have played.

How points work

Points are scored the way a real table keeps score.

You win: you collect the value of your hand from each of the other three players. Whoever threw your winning tile pays double, and everyone pays double if you picked it yourself. A hand with no jokers is worth double.
A computer player wins: you pay them the value of their hand, so your score goes down.
Wall game (nobody wins): 0 points.
A day you don't play: 0 points.

If two players tie on points, the one with more wins is ahead. If that's a tie too, the faster player is ahead.
