Waitlist and fines
- How does the waitlist work?
- Once the game hits its max, tapping In puts you on the waitlist. Your place is when you tapped.
- What happens when a spot opens?
- It’s held for the next person. The card’s message names them, and they tap Claim spot or Drop.
- How long do I have to claim?
- 2 hours, or 30 minutes if the game starts within 3 hours. It ends at the start time, but you always get at least 15 minutes.
- What if I miss it?
- The spot passes to the next person. Tap Rejoin to get back in line. The organizer can also re-offer it.
- How do no-show fines work?
- The organizer can set a fine. After the game they mark who didn’t show. You pay it with Venmo or Cash App, tap I paid, and you can tap In again.
- Does a fine follow me to other groups?
- No. A fine only follows you within the same group chat.
Known limits
| Limit | What to do |
|---|---|
| Android can’t open the card | Roster and pay texts are plain text, so everyone gets them. |
| Names aren’t filled in | Paste the group list once. |
| Typed “in” isn’t counted | The organizer can flip that person’s switch. |
| “Paid” is self-reported | The organizer can toggle Paid. |
| No push alerts for open spots | The card’s message names who’s up. If nobody has sent a card since, opening it shows your Claim button. |
| Fines stay in one group chat | They also stay with your iPhone. The organizer can waive or mark paid. |
| About 40 people per game | The game lives inside the message, which has a size limit. |
