🏓 Ladder Match Chaos - [3 Hours]! 🌅🎉 (Havelock)
🏓 Ladder Match Chaos - [3 Hours]! 🌅🎉 (Havelock)
### Pickleball Sunset Ladder Mixer! 🏓🌇 An evening of dinks, (drinks after maybe), and a ladder format designed to expose your ego in public. 📍 Location: 317 Outram Rd, Holiday Inn Singapore Atrium, Singapore 169075 🕓 Time: 4PM to 7PM 💵 Cost: $25 per person ($5 paddle rental if you don’t have your own trusty weapon) Early bird: $20 (excluding paddle) if you confirm with payment at least 5 days before the event Lock in your spot (payment = confirmed, no payment = vibes only): 📲 Early Price: [https://hitpay.link/bpufbo](https://hitpay.link/bpufbo) 📲 Normal Price: [https://hitpay.link/gy1dej](https://hitpay.link/gy1dej) ✅ If you usually pay cash, no worries, just continue with that. ⚠️ Cancellation Policy Please give at least 24 hours’ notice for cancellations to receive a refund. No refunds for no-shows or cancellations within 24 hours, unless the whole event is rained out. ### ## 🪜 What’s the Plan: Rookie → King’s Court Ladder This is a ladder mixer. Everyone starts humble. Nobody starts as a “king” (yes, even you). Courts: Rookie Court: your spawn point King’s Court: final boss arena ### 🎮 How it Works 1. Start at Rookie Court 2. Win a game = you upgrade to King’s Court 3. Lose at any point = back to Rookie Court (character development arc) 4. On King’s Court: max 3 wins After 3 wins, you restart at Rookie Court again (so you don’t camp and become a court landlord) ### 🌀 Paddle Queue System All courts run on paddle queue. Put your paddle in the box/line for the court you’re queuing for. Rotate in when it’s your turn. No cutting, no politics, no “I know the coach”. ### 🧮 Scoring + Timing Scoring: First to 15, rally scoring (no serving maths, we’re here to play not do accounting) Timing: Each match capped at 15 minutes so everyone gets runs ### 🏆 Official Tournament Balls Franklin X-40 for all games. ### 👑 Ladder Champions + Prize We’ll track King’s Court streaks and crown the Ladder Champions. Small token prize included (mainly for bragging rights + group chat supremacy). May the champions rise. May the excuses be creative. ### 📌 Rules of the Game Switch it up: new partner, new opponents after each match Be nice: friendly competition, not SEA Games Call lines fairly, replay if messy, keep it moving *** ## Why You’ll Love It Fast rotations, lots of games Meet a bunch of kakis without awkward small talk You get the dopamine of “ranked mode” without downloading anything *** ## What to Bring Your paddle (or rent one) Water bottle, don’t faint halfway Your best “aiyah nvm” attitude when the ball goes sideways A ready-made excuse for when you get sent back to Rookie Court 🔔 Friendly Reminder Pickleball is a social and physical activity, please be mindful of your own safety and physical limits. Participation is at your own risk. Stay hydrated, warm up properly, and rest if you need to. 🎟️ RSVP Now — Spaces Are Limited!
