FEATURES
Draws, pricing, prize swaps, shipping — the system runs the whole flow. You just add prizes.
The iron rule of ichiban kuji: no losing tickets. From Prize A down to the entry tiers, every draw puts a prize in hand — every point spent pays back something.
The price is recalculated after every draw and can only drop, never rise. The later you join, the cheaper it gets — players chase, sets sell out.
Winning positions are randomly assigned and locked at launch. Merchants cannot see or change them — players draw with confidence, you never have to prove innocence.
Players can trade unwanted prizes back into points and keep drawing for the big one — the value stays in your store and fuels the next round.
An atomic lock guarantees a single active player; everyone else sees live watcher counts and a hold countdown. Fair racing, no overselling.
Players submit addresses online, you manage shipping in one dashboard, and a notification email goes out automatically the moment you ship.

FAIRNESS
Fairness is the lifeline of a kuji business. We take the decision out of human hands — the system decides, and every draw goes on record.
When a set is created, top-prize positions are randomly distributed across all tickets — no human touch, ever.
Positions are locked at launch. Neither the merchant dashboard nor players can see where a prize landed — it is revealed only at the moment it is drawn.
Each draw logs its sequence number, remaining prizes and the price at that moment — the full history is there to check, draw by draw.
