There are many ways to play Urobo™, but probably the most basic one is Urobo Even-odd.
There are no strongest or weakest tiles.
The strength of each tile depends on their position to the one that had been laid.
You will have to swap in the next game.
The ones that follow the played one clockwise are stronger, and the other ones counter-clockwise are weaker.
Try to pass a trick to avoid leading the next one.
Remember you can always lead a weak tile.
In case of equality the one who won the last trick wins the deal.
