QR CODES THAT MAKE SENSE AT A PARTY
One private pack. However your party likes to play.
The Party Pack adds cameos and a shared celebration to all three games. You receive one private host link and a matching printable QR sheet in the same portal-and-world style as the hero above. Play on one device, let guests scan on compatible devices, or cast/project it with the setup you already know.
- 01
The host tests first. Open the private link on the phone, tablet or computer you plan to use before guests arrive.
- 02
Put the cards where the action is. Print the included table cards, favor tags or one big “scan to play” sign.
- 03
Choose the party setup. Guests can scan on compatible devices, everyone can watch one screen, or you can cast/project using your own equipment.
- 04
The birthday hero stays the star. Up to four guest cameos can appear only with grown-up permission.

This is the moment you’re buying.
Open the host link on a compatible phone, tablet or computer. If you already know how to cast or project that device, the room can watch together; if not, the game still works as a close-up play-and-pass moment. We provide the private game and QR cards, not hardware, controllers or on-site setup.

MADE FOR KIDS. CONTROLLED BY GROWN-UPS.The magic is theirs.
Read the parent privacy promise →
The magic is theirs.
The controls are yours.
Kids never make an account, land on an email list, or talk to strangers. You reserve it, you approve it, you decide when they see it, and you can ask us to delete it any time.
01No kid accounts
Grown-ups buy it and fill in the details. Kids never sign up for anything.
02Photos are optional
We can draw from details alone, or use an approved family photo if a grown-up asks.
03Private by default
A secret link only you share. It never shows up in Google.
04Clean play pages
No ads, no tracking, and nothing for them to buy.
Our promises
We hit the date
Send us your answers and your yes by the dates we give you. If we then miss the date we promised and it’s our fault, you pick: full refund, or a free bump up to the next package.
It actually plays
If the finished game won’t run on the phones, tablets, or computers we listed — and we can’t fix it before the party — you get your money back. Anything broken, we fix free, always.
Every detail right
Got their favorite color wrong? Misspelled the nickname? We fix it, free. If you change your mind about the art or the story after you’ve approved it, that uses the revision that comes with your package.
These are the commitments that back every paid package — full details in the terms of sale.
DIRECT FROM THE STUDIO
Reserve the big day. Pay only after we confirm it.
Tell us the occasion, month and package. A grown-up from the studio will confirm whether the date and scope fit before we send any payment link.

date check before payment
Every game has a real delivery deadline. We confirm the window first instead of inventing scarcity or taking money for a slot we cannot prove.
GROWN-UP QUESTIONS
Before you press play.
When do I pay?
First we confirm your event date and package. Nothing is charged through the reservation form; we send a secure Stripe checkout link only after the delivery window is confirmed.
Who is building these games?
A human-led Muse Nexus studio working with AI collaborators for code and original artwork. We shape each game around the grown-up’s brief, review the result, and play it through before delivery.
Can you make a game with a famous character?
No. Every Big Day Arcade world and hero is original. Tell us what they love—racing, animals, magic, space—and we’ll create a fresh world with that energy.
Do I need to upload a photo?
No. A nickname, colors and favorite things are enough. If a grown-up wants an approved child or family photo used for an in-game cameo, we can arrange a private transfer after ordering. It is optional, used only for the game you approved, never added to advertising, and deletable whenever you ask.
Will it work on phones and tablets?
The games have touch and keyboard controls for modern phone, tablet and desktop browsers with 3D support. Try a short sample on your device first; the ordering grown-up also approves the private game before delivery.
What if the birthday is very soon?
Tell us the date. If we can honestly make it, we'll offer you a rush spot. If we can't, we'll say so — we'd rather turn down the money than miss the big day.
Is this a subscription?
No. The package price is one time and includes 12 months of private hosting. We’ll ask before any optional renewal.
How do party QR cards work?
The grown-up host gets one private party link and a printable sheet of scan cards. Guests can scan the host-controlled code on compatible devices, or everyone can watch one device together. You decide whether and how to cast or project it using equipment you already have; Big Day Arcade does not provide party hardware or on-site setup.
What happens after I reserve?
We confirm the date and scope by email. When checkout is open, you pay securely with Stripe, complete the adult brief, approve the Game Card, then receive a private link to test before the big day.
