A personalized game gift for your sister for her birthday: your memories as a level they can play

What the game looks like

Photos show a moment; a game lets her walk through it. oin builds a small pixel world around your story, with her as the main character, so the memories are a place she moves through rather than a slideshow.

Under the hood it is a short pixel game with levels, a quiz and a final level in Almaty, Kazakhstan. You supply the photo, the letters, the questions and, if you like, two NPCs; New York and Tokyo final levels are coming soon.

What to write in the two letters

Use the first letter to set the scene of how it began. Use the second for where you are now and where you hope the story goes.

Five quiz questions to start from

Pick the five questions from different years so the quiz itself tells the story in order.

• What did we get wrong about the road trip?
• Who always loses at the board game?
• Which holiday do we still talk about?
• Which dish is the family favourite?
• Which song played in the car?

If the birthday is tomorrow

Leaving it late is easy to fix: Gift cards, flowers and a personalized game arrive fast, and an oin game is usually emailed within an hour of payment. Add a cake or a card for the table.

Think of the day as a whole: a morning surprise, a gift at dinner and something for the evening. A single gift rarely feels like enough on its own.

Why it suits your sister

A sister has the longest shared history in your life, so the game can be as silly as you like. Childhood nicknames and family legends make the best quiz questions.

Let the first letter tease and the second say how much you actually rely on her.

How to make it, step by step

• Upload an authorized photo of her; the main character is generated from it.
• Write two letters, the first for the opening room and the second for the end of the final level.
• Add a 5-question quiz about your shared memories; each correct answer is rewarded with flowers.
• Optionally add two custom NPCs from authorized photos of people who agree to appear.
• Pay $29.90 once; the game is generated automatically and usually emailed within an hour.

Price, delivery and refunds

It costs $29.90 as a one-time payment, with regional pricing and no subscription. Payment runs on a secure Polar checkout and Polar is the Merchant of Record, so oin never sees your card. After payment the game is generated automatically and emailed, usually within an hour, as a private link that stays available for one year plus a downloadable copy. If generation fails, the payment is refunded automatically. All sales are final once delivery starts, but you get a full refund if the game cannot be generated or delivered, if you are charged twice or if it is faulty and cannot be fixed. See the refund policy.
