Lottery sales app for Shopify
YUINAR
Fair lotteries for limited drops. YUINAR lets Shopify merchants run the whole flow — entries, the draw, and purchase links that only winners can use — from the store admin.
The app's admin, entry pages and emails are currently available in Japanese only.

Built for these problems
Traffic spikes the moment a drop goes live
Entries are accepted over an entry period and then drawn, so customers don't have to race for the first seconds.
Scalpers buy up stock before real fans can
Winners get a purchase link by email that only they can use.
Running draws with forms and manual emails is exhausting
From entries to win and lose notifications, everything runs from your store admin.
Who it's for
Stores whose products have more fans than stock: handmade tableware, glass and crafts, limited-run sweets, food and drinks, collaboration or limited apparel, garage-brand outdoor gear, and more.
Features
Entries to purchase, all in your store admin
Set the product, entry period, number of winners and purchase deadline, then publish. Entries open and close automatically.
Purchase links only winners can use
Winners automatically receive a dedicated purchase link by email, which helps prevent scalping. Winners who haven't purchased get a reminder 24 hours before the deadline.
Member-rank weighted draws
Register Shopify customer segments as member ranks. Give higher ranks more entries to raise their chances of winning, or limit who can enter.
Two ways to enter
Share an entry page link by email or social media, or add an "Enter the lottery" button to the product page.
Duplicate entry prevention
Duplicate entries to the same campaign are blocked automatically. If different customers enter with the same email address, the entry is flagged for review rather than rejected, so your store decides.
Automatic win and lose notifications
Win and lose emails are sent automatically. Win emails include the product image and the purchase link.
Announcements for new campaigns
Email customers who opted in to announcements about new campaigns. Every email includes an unsubscribe link.
Encrypted email addresses, Japan time
Customer email addresses are stored encrypted. All dates and times are handled in Japan Standard Time.
