Portbound — Raffle Drop Rates
Last updated: 2026-09-22
This page lists the odds and rules for every prize in the Harbor Raffle (港邊摸彩) in Portbound (回港). The raffle involves no payment, but we publish the full odds anyway.
- Raffle tickets come only from diving and completing quests. They cannot be bought with real money. The iOS version does sell diamonds as an in-app purchase, but diamonds buy neither tickets nor pulls — they buy sea coins, cold-store space and market forecasts.
- Every prize is an in-game item. No physical prizes are shipped, and prizes have no connection to real money and cannot be exchanged for cash.
Banner: Harbor Raffle
- Period: permanent
- Cost: 5 raffle tickets per pull; 50 raffle tickets for a 10-pull
- A 10-pull is the same as 10 single pulls in a row: every pull has the same odds as a single pull, with no extra rarity guarantee.
The game is shown in Traditional Chinese; each prize's in-game name is in parentheses.
| Rarity | Prize | What you get | Rate per pull |
|---|---|---|---|
| N | Live shrimp bait (活蝦餌) | +10 bait | 40.0% |
| N | Sea-coin pouch (海幣袋) | +80 sea coins | 32.0% |
| R | Spare line (備用魚線) | +1 spare line | 14.0% |
| R | Harbor lamp (港燈) | Unlocks the harbor lamp boat skin (+60 sea coins if already owned) | 10.0% |
| SSR | Night-dive look (夜潛外觀) | Unlocks the night-dive look (+300 sea coins if already owned) | 2.0% |
| SSR | Jackpot (頭獎) | +500 sea coins | 2.0% |
| Total | 100.0% |
Totals by rarity: N 72.0%, R 24.0%, SSR 4.0%.
Pity
Counting from your last SSR, pull 80 is guaranteed to be an SSR: the night-dive look if you don't own it yet, otherwise the jackpot. Getting any SSR (night-dive look or jackpot) before then resets the pity count. Single pulls and 10-pulls add to the same pity count.
New accounts start with a pity count of 0 (the raffle stall shows 0/80). A new account has no raffle tickets; tickets are earned by diving and from daily quests.
Duplicates
- Winning the night-dive look again when you already own it gives +300 sea coins instead.
- Winning the harbor lamp again after it is unlocked gives +60 sea coins instead.
- The results screen marks each prize as new (NEW) or shows the sea coins a duplicate turned into.
- Live shrimp bait, sea-coin pouches, spare lines, and the jackpot give the listed amounts every time.
Notes
- The rates above match the weights the game actually uses. The in-game raffle stall also shows the rarity totals and the 80-pull pity.
- Rates are theoretical per-pull probabilities; pulls are independent except for the pity rule.
- Game progress (including raffle tickets, items, and the pity count) is saved on our server with your account, so it carries over whenever you sign in with the same account. Deleting your account deletes this progress permanently; if you sign in again afterwards, you start as a new account with the pity count back at 0.
- Any change to the odds or rules will be announced on this page and in the game before it takes effect.
- Users under 18 should use the App with a parent or guardian's consent.
