How is Shinobi Bout played?
It is essentially Uno with some small tweaks.
You are trying to play numbers, in order.  If you have a "run" of numbers in the same suit (color), you appear to be able to play them all at once.
There are cards that allow you to change the color, even a wild draw 4.
In the anime, you see Boruto play a change color card with a "skip" card skipping the next player's turn.  It appears the cards are numbered from 1-10 in five colors.
