Yes, in the Custom mode you can change the game as you like and, for example, make settings for card assignment. For the scoring method, you can choose between the existing methods of the rule sets (Mau Mau, Crazy Eights, 101, etc.) or play without any.
The settings apply to both offline and online games. In online mode, the rules of the person who created the room and started the game apply.
You can find the Custom mode as follows:
- Open the menu in the upper left corner of the main screen of the app
- Select the button "Settings"
- Tap on one of the arrows next to the current rule set name (above the player number) until it says "Custom"
- Tap on the desired options (scoring method, target score) to make your selection
