This is a glitch that can be used to make money in Yahoo! Puzzle Pirates. Unfortunately, this glitch cannot be used with X amount of POE/Doubloons. However, it works, and that's what counts. The good part about this glitch is that it works on ANY ocean. I'll repeat that; ANY ocean. Just follow the instructions below.
1: Login to your YPP account. Please note that the probability of this glitch working is greatly reduced if playing in your browser.
2: Go to the "Ye" tab on the right sidebar and click "Notice Board".
3: Click the "Puzzles" tab and select the bilging puzzle, and then the "Play Now!" button. You will immediately be transported to a ship.
4: Find a bilging station on the ship. If all are taken, look for a bilger with a white name (AI). Click them, and click the "Ask to move" button. If there are no pirates with white names occupying the bilging stations, repeat steps 2 and 3.
5: After starting the bilging mini-game, just do nothing and stay idle.
6: After 1 league (when the ship pauses), leave the ship by clicking the "Ye" tab and clicking "Go Home".
7: Navigate to the nearest bank. Upon entering, attempt to buy a Doubloon. Do not buy one, but log the amount of POE you would receive.
8: Navigate to the nearest Inn. Once there, find an AI (Player with a white name). Click on the "Say" button next to the chat box and select "Tell". Type in the name of the AI in the first box and in the second box type "Help!" without the quotes.
9: Click on the "Say" button next to the chat box and select "Say". In the chat box, type "/pay [name] [poe]" (without the quotes), replacing [name] with the name of the AI and [poe] with the amount of poe logged in step 7. Push Enter/Return.
10: Click the "Ye" tab and select "Go Home".
12: Wait 5 minutes.
13: Log back in. Your account should be credited with the amount of poe logged in step 7. Note that this does NOT work if the amount of poe found in step 7 is replaced.
