GameKing is event-operations SaaS built for associations, chambers, guilds and social clubs. Automatic LINE Flex tickets, personalised QR check-in and automatic payment reminders, with a 1% fee only, no monthly fee, live within 24 hours.

Pain points · What happens every day

If any of these sound familiar, GameKing was built for it.

Excel lists flying in every version

Signup sheet, payment sheet, seating sheet: three Excel files, edited daily, and nobody knows which one is right.

Chasing payments one message at a time

The week before the event you remind each unpaid member on LINE, tick them off once paid, and stay up late before every monthly meeting.

Hunting names on the check-in list

A stack of printed lists, members waiting while you flip through them, and new members are worse.

Reconciliation that drives you mad

Cash, transfers, cards and LINE Pay all mixed together; accounting spends 3 days reconciling at month end.

Features · Six core capabilities

Every feature was shaped by a real user pain point.

Event live in 5 minutes

Enter title, date, capacity and price in the admin; a signup link and payment page in 5 minutes.

Automatic LINE Flex tickets

Payment done, a personalised LINE Flex Message goes out: event info plus entry QR code in one card.

Personalised QR check-in

Scan the QR on site and it shows “Welcome Wang Xiaoming / guest No. 3”; check-in records sync to the admin instantly.

Smart automatic reminders

LINE reminders go out 24h before the deadline and when fewer than 10 seats remain; anyone who has paid is excluded.

1% transaction fee

The market charges 5%, we take 1%, with no monthly fee, no listing fee, pay as you go.

Full reconciliation reports

Export payment details, entry records and refunds in one click; accounting reconciles in 30 minutes.

How it works · The process

Four steps from start to running.

  1. STEP 1
    Register your organisation

    Enter basic details and connect LINE Pay / credit card; approved within 24 hours.

  2. STEP 2
    Create an event

    Enter title, date, venue, price and capacity; signup and payment links in 5 minutes.

  3. STEP 3
    Share the link + collect automatically

    Post the link in a LINE group or FB group; members sign up and pay themselves, and the system sends the tickets.

  4. STEP 4
    On-site QR check-in + reconciliation

    Scan the QR to check in on the day; export the reconciliation sheet for finance in one click afterwards.

Use cases · Who it fits

Not sure it fits you? Start with these scenarios.

BNI / Rotary / Lions chapters

Weekly meals, quarterly dinners, annual events: 50+ a year, all automated.

Teams / softball league games

Entry fees, deposits, field fees and meals collected in one go; QR check-in on the day, no roll call.

Guilds / trade associations

Board meetings, industry talks, annual assemblies: too many members to remember, so let the system do it.

Clubs / alumni dinners

Run an event whenever you feel like it, without flinching at the admin. Up to 500 people per event, still easy.

FAQ · Common questions

About GameKing, the questions we hear most.

Another question? Leave a message at the foot of the page; we reply within one business day.

We are a small group with few events. Is it worth it?

Yes. No monthly or annual fee, and no event means no charge. Even 1 event a year for 30 people works.

Can we take cash / bank transfer?

Yes. Online payment supports LINE Pay, credit cards and convenience stores; if a member chooses cash on site, the system marks it “to settle on site”.

What if a member does not use LINE?

Tickets are emailed too. At check-in you can search by name or the last 4 digits of a phone number, so LINE is not required.

How are refunds handled?

One click to refund in the admin; the provider fee is already covered by the 1% and is not charged again. Refund records are fully auditable.
