About Saisei
You inherit a diner that is going under.
In the morning you decide how much to prep and what to charge, and pick one move for the day.
At noon you open the doors and watch who sits down.
At night you read the ledger. Sales, ingredients, wages, rent. What is left?
You repeat this for 12 days, then close the books.
The point is not to play well.
The point is to find out why this place is failing, before it does.
Before the final reckoning you name your verdict.
Nobody knows the place? Ingredients cost too much? The prices are wrong?
Which line of the ledger bled the most? Which customer's remark gave it away?
Every cause you name correctly is recorded, and unlocks new moves for the next run.
So the first run does not have to be saved.
You learn this diner by losing it.
What you do
- Set prep counts and prices every morning
- Pick one move a day from 57 cards (flyers, menu revisions, hiring, more seats, and so on)
- Unlock eight shelves of moves as you play
- Read cost ratio, labor ratio, waste and seat occupancy every night
- Collect 45 causes of failure and 13 titles
- Choose a run length of 9, 12 or 18 days
- Daily diner: the same shop for everyone that day
Notes
- One purchase. No further charges.
- No ads.
- No network needed. Saves stay on your device.
- Japanese and English.
- One hand, portrait.
