Key Takeaways
- Scenario 372 is darts oche OTP at 19:40 — not snooker 15:05, escape-room 11:20, table-tennis 18:20, or badminton 19:10.
- A 19:40 door PIN that waits behind a “league merch” CSV looks like the keypad is dead.
- Priced by devices and SMS send volume. You use your own phone and operator SMS credit. Free is 300 SMS lifetime, 1 device. Developer is 25,000 SMS per year.
- Starter is 2 devices; the desk spare still counts.
- Hold gift-card and waitlist until oche OTPs drain.
- Canary the desk SIM at 19:20, not at last night’s booking job.
Summary
Scenario 372 is a darts pack: oche PIN at 19:40, guest codes after, league merch held until OTPs drain. Service pricing is based on device count and total SMS sent through the gateway. You need a working Android phone with a SIM and SMS credit from your mobile operator. Operator message costs are yours—we do not sell carrier SMS balance.
A 24-row “league night” file that starts at 19:05 will make the 19:40 door code look like the radio is dead.
Not a CodeCanyon “salon OTP” pack. Device meters apply — Twilio vs Android SMS gateway.

Context
First throw is 19:50. Players queue at the door from 19:25. Retail still wants a waitlist CSV.
Free (300 SMS lifetime) is a rehearsal club. Developer is 25,000 SMS per year.
Core scenario guidance
19:40 is darts OTP, not snooker 15:05 or badminton 19:10. Timezone is the club, not the franchise HQ.
Darts OTP lanes
| Lane | When | Typical fail |
|---|---|---|
| 19:40 oche PIN | Club local, before first throw | Phone in a locked dart cupboard after dinner |
| Guest / late code | After PIN depth is low | Merged into the merch blast |
| Staff OTP | Transactional, own pool | Dumped onto the oche radio |
| Waitlist / merch | Held until last oche DLR | Released at 19:05 into auth SMS |
Cost and ownership
Priced by devices and SMS send volume. You use your own phone and operator SMS credit. The desk spare is a billed device. Duplicate PINs burn airtime.
Name a 18:45–22:00 on-call for evening throws, not only weekday admin.
Operations
19:20 canary. Abort: hold waitlist, keep staff OTP, skip a second “all boards” blast. Do not “resend PINs.”
Security and compliance
Short codes. No full booking bodies in shared chat. Waitlist CSV is promotional — STOP still applies.
Decision guide
Ship when 19:20 canary is green and OTP depth drains before merch. Delay if the desk phone sleeps in the dart cupboard. If handsets are forbidden, CPaaS for staff OTP.

- Throw-wave on-call named.
- Device cap includes spare.
Next steps
Review device and SMS volume pricing, device setup, SMS API documentation.
Deep dive: production hardening
A dinner lock on USB is an outage at 19:40. Watch DLR, not booking 200s.
Deep dive: scaling and failure modes
Two-site clubs add devices before inventing a hidden unlimited-handset SKU. Raise OEM ceilings; fair-use remains.
Deep dive: integration discipline
Idempotency on booking_id + kind (pin|guest). MCP is a REST wrapper — live fields in Developer Center.
Priced by devices and SMS send volume. You use your own phone and operator SMS credit.
19:20 darts drill
Canary. Fire one oche PIN. Confirm DLR before waitlist CSV. Hold merch during the wave.
