Mario Party Overlay Tutorial

In this page all the basics of MPO are explained.
Settings are explained here.

Page Layout

You can click on the numbers to increase it (called counters), by holding Ctrl or checking the 'Minus' checkbox it decreases the counters instead.
To change the amount added/subtracted you can click on the numbers at the top, pressing the number on the numpad changes it too (0 for 10). To give/take the coin-star you just click on the character.

The "Generate & Copy" button outputs all counters as text, and copies it, so you can paste it in a stream chat to track the Bonus Stars for them as a example.

The Save/Reload buttons save and reload all stats (not characters, not settings, only stats) and reloads them. They will be saved in your browser too and automatically loaded the next time you open the site.

Note: All settings are applied immediately, the save button will only save it permanently as otherwise they get reset when you refresh the site.

Change Characters/Counters

If you want to change the characters or counters you can click on the "Character & counter options" buttons at the top left.
Then you can select your character for each player, click on "COM" so it's a Computer. Click on "Counter Options" to change the counters. Click on the counters to hide or show them, even if counters are hidden, they still save everything.
Below that you can permanently save all characters and counters (after reloading the page it will automatically load it) and reset them (this will also get rid of the perm. saved characters and counters).

Highlighting

This feature automatically highlights the player that got a certain bonus star. This is on by default with the color red which can both be changed in the settings.
