Instructions & Tips:

• Choose a version from the menu on the right.
  • Ruby/Sapphire and Emerald technically have the same river layout, but the rest of the route has some minor differences.
  • Omega Ruby and Alpha Sapphire have the same layout as Ruby/Sapphire/Emerald, and Brilliant Diamond and Shining Pearl have the same layout as Diamond/Pearl/Platinum, so this tool can be used for those games as well. (However, in Omega Ruby/Alpha Sapphire, you can bypass the random tiles entirely by simply fishing under the bridge during the day for a 100% Feebas encounter rate.)
• On desktop:
• Click once to place an "X" on the tiles you have already checked.
• Right-click once to place a Feebas sprite on the tiles where Feebas can be found.
• Double click to remove the marker from a space.
• You can also move Brendan or May around if you want to use them to keep track of where you're at.
• On mobile/touch device:
• Tap once to place an "X" on the tiles you have already checked.
• Tap and hold to place a Feebas sprite on the tiles where Feebas can be found.
• Double tap to remove the marker from a space.
• The trainer sprites cannot be dragged on mobile.

Note that if your game has a functional battery, the locations of Feebas in Ruby/Sapphire/Emerald will change if the trendy phrase in Dewford changes (which has a chance of happening daily). In Diamond/Pearl/Platinum, the fishing spots change every day (and there is no internal battery that can die to pause this). In either of these cases, this tool may not be helpful if using over an extended period.

Happy fishing!
