Dominoes Deluxe offers several modes and configurable settings, which matters in dominoes because the game varies by region — draw versus block, all-fives scoring versus plain, different hand sizes.
Being able to set the rules explicitly means you can play the version you actually grew up with rather than whichever one the developer preferred.
The main ones — draw versus block play, and different scoring modes including all-fives, where open ends totalling a multiple of five score points.
You score whenever the numbers on the open ends of the chain add up to a multiple of five. Doubles count both halves, so a double-five end contributes ten.
Yes — drag and drop tiles. Nothing to install.
