For those (like me) who have asked before for a complete set of rules of what the cards do, if you hover over the cards you get a text which says what each does.
EXCEPT there are two slight errors and one change. After a ten is played the ribbon says "Next player must discard without effect"; a similar message is posted when you have no legal move. But in each case, if you discard a 10 the next player still has to discard.
The change is an important one and sometimes affects the card 7 (new variation). It is reported properly in English but not yet in French (don't know about other languages) If this variant is selected the following applies: You can still stop your move at any point up to 7 squares, and any card in the way is still eaten - but you don't now get the rest of your move - it's one move of up to 7 spaces.
Sorry - couldn't find the place to report this under Bugs!
