The simplest kids birthday party checklist has four checkpoints: book the package, date and location 4–6 weeks out; confirm invites and headcount 2 weeks out; sort the cake and snacks the week of; and arrive 15 minutes early on the day for the briefing and waivers. At CipherX, every package is a flat rate, from $250 for 6 kids to $400 for 10, with extra kids at $40 each (subject to capacity), so the budget is simple to plan.
Work through the list below from top to bottom. The packages and prices are identical at CipherX Coquitlam and CipherX Delta.
4–6 Weeks Out: Book the Essentials
- Pick a package. Every party is 2 hours in total with dedicated staff support. Packs A, B and D are 1 hour of activity plus 1 hour in a private party room, while the Slime Party includes 2 hours of party room with its 90-minute workshop inside that time.
| Package | Kids | Flat price | What’s included | Ages listed |
|---|---|---|---|---|
| Pack A: Birthday Adventure | 6 | $250 | One activity: escape room, free-roam VR, X-Grid or splatter room | Varies by activity |
| Pack B: VR Party | 6 | $250 | 1 hour of free-roam VR, pick 4 games | 8+ |
| Pack C: Slime Party | 10 | $350 | 90-minute Slime Chef workshop, 2 take-home slimes per kid, lab coats and goggles | 5–14 |
| Pack D: The Crew | 10 | $400 | One activity: escape room, X-Grid or splatter room | Varies by activity |
- Pick a date. Weekends fill 2–4 weeks ahead, especially for 10-kid parties, while weekdays are usually open within a week.
- Pick a start time. Monday to Thursday, Coquitlam opens at 2 PM and Delta opens at 12 PM, so after-school parties work at both. On Fridays both open at 12 PM, and on Saturdays and Sundays Coquitlam opens at 12 PM and Delta at 11 AM.
- Pick a location. CipherX Coquitlam is at 1065 Ridgeway Ave, and CipherX Delta is at 7949 120 St (Scott Road) on the Surrey border. For older birthday crews, Delta also has axe throwing and a golf simulator to add.
- Match the activity to the kids. The Slime Party is for ages 5–14, the VR Party is 8+, X-Grid is for ages 5+ (under 16 with an adult), and the splatter room has no age restrictions. Still deciding? Browse our kids birthday party ideas.
- Join CipherX Rewards. CipherX Rewards is free, earns 1 point per $1 and includes a free game on your birthday.
2 Weeks Out: Invites, Headcount and Details
- Send invitations with the location address, the start time and a note to arrive 15 minutes early.
- Set an RSVP deadline a few days before the party so you can confirm numbers in time.
- Collect dietary needs. You bring the cake and food, so you will be planning around allergies and preferences yourself.
- Confirm your headcount. Extra kids are $40 each, subject to capacity. For 15 or more kids, contact CipherX for a custom quote.
- Share what to wear. Closed-toe shoes are required for X-Grid. Splatter room suits and gear are included, and slime parties provide lab coats and safety goggles.
- Send the waiver link. Ask parents to complete the online waiver before the day so check-in is quick.
- Line up adult helpers. One or two extra adults make the party room hour easier, especially with 10 kids. If you chose X-Grid, remember that players under 16 need an adult with them.
Party Week and Party Day
The week of the party
- Order or bake the cake. Outside cake and food are welcome.
- Plan simple party-room food: finger foods and drinks that are easy to serve within an hour.
- Pack plates, napkins, cutlery, candles and a lighter if you need them, and ask our team what the party room has when you confirm.
- Decide on favours. Slime parties already send each child home with two custom slimes, and the splatter room includes a take-home canvas, so you may not need goody bags.
- Reconfirm your time, location and final headcount.
Party day
- Arrive 15 minutes early for the briefing and waivers.
- Bring the cake, candles, food, drinks and a bag for gifts and take-homes.
- Check shoes: closed-toe for X-Grid.
- Know the flow: 1 hour of activity, then 1 hour in the party room. For slime, the 90-minute workshop runs inside 2 hours of party room time.
- Let the staff run the activity so you can enjoy it and take photos.
After the party
- Send thank-you notes, and share photos with other parents if they are happy for you to.
- Jot down what worked for next year: the activity, the headcount and how much food you actually needed.
Budget Worksheet With Example Math
Because every package is flat-rate, budgeting is mostly arithmetic. The totals below are example math built from the published prices, and extra kids are always subject to capacity.
| Scenario | Package | Example math |
|---|---|---|
| 6 kids, VR party (ages 8+) | Pack B | $250 flat |
| 8 kids on X-Grid | Pack A + 2 extra kids | $250 + (2 × $40) = $330 |
| 10 kids, slime (ages 5–14) | Pack C | $350 flat |
| 10 kids on X-Grid or splatter | Pack D | $400 flat |
| 12 kids, slime | Pack C + 2 extra kids | $350 + (2 × $40) = $430 |
| 15+ kids | Custom | Contact CipherX for a quote |
One useful break-even: at 10 kids, Pack A plus 4 extra kids would be $250 + (4 × $40) = $410 in total, so Pack D at $400 flat is the better deal once you reach 10. VR is not on the 10-kid package because VR runs 6 headsets at a time, but it can be added as an add-on with kids rotating through. The Splatter Battle upgrade is $150 flat. Then add your own lines for the cake, snacks, drinks and invitations.
Common Mistakes to Avoid
- Booking a weekend too late. Weekends fill 2–4 weeks ahead, so a Saturday party booked the week before may not have the slot you want.
- Inviting more kids than the activity holds. VR runs 6 headsets at a time, room pages list 2–6 players per escape room, and X-Grid takes 2–10 players.
- Forgetting shoes. Closed-toe shoes are required for X-Grid, so put it on the invitation.
- Arriving right at start time. Arrive 15 minutes early so the briefing and waivers do not cut into party time.
- Leaving candles at home. Assign one adult to cake duty so the candles are lit when the kids walk into the party room.
