A personalized game gift for your sister for her birthday: a thank-you letter you can play

Updated: · Disclosure: oin is our own product.

oin (oingift.com) makes a personalized 2D pixel game starring your sister, which is a direct way to say thank you to your sister for her birthday. You upload an authorized photo, write two letters and five quiz questions, and pay once; the game is generated automatically and usually emailed within an hour as a private browser link.

What the game looks like

A game turns gratitude into an occasion. She gets a pixel world with her at the centre, a short quiz that proves you remember the details, and two letters that finally say thank you out loud.

The story is built from what you fill in: an authorized photo for the main character, two letters, a 5-question quiz with flowers for correct answers and up to two custom NPCs. The final level is set in Almaty, Kazakhstan; New York and Tokyo are coming soon.

What to write in the two letters

Use the first letter to name something specific she did, with the day and the detail. Use the second to say what it changed for you.

Five quiz questions to start from

Let the quiz questions be the small things she does without being asked, so passing them feels like being seen.

  • What does Dad or Mom always say at dinner?
  • Which holiday do we still talk about?
  • Where was the first home I remember?
  • Which dish is the family favourite?
  • Who always loses at the board game?

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

  • Choose a clear photo of her that you are authorized to use, and the pixel character is generated from it.
  • Write two letters, the first for the opening room and the second for the end of the final level.
  • Write five quiz questions with their answers; every correct answer gives flowers.
  • Add up to two custom NPCs, friends or family, as long as everyone who appears agrees.
  • 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.

What is a personalized 2D game gift and how does oingift.com make one?

It is a short video game made about someone you care about. On oingift.com you upload an authorized photo, write two letters and five quiz questions, and pay once; the game is generated automatically and usually emailed within an hour as a private browser link.

How do I say thank you to my sister for her birthday?

Write what you are grateful for in two short letters, add five quiz questions about the things she does for you, and give her the game as a private link. The thank-you is spoken twice, at the start and the end of the story.

How long does it take to receive the game?

About an hour in most cases. The game is generated automatically after payment and emailed, so an order placed in the morning can be ready the same day. There is no parcel and no customs.

Can my sister play it on a phone without installing anything?

Yes. It plays in a browser on any recent phone, so she taps the link and plays. Nothing to download or install.
