The first four exercises use our original study agreement: 32 cards, wild jacks, non-stacking sevens and skipping eights. Four extra exercises then explicitly switch to other house agreements. Read each stated rule first; do not transfer its answer uncritically to another ruleset.
In this guide
Exercise 1: red is not a suit
On hearts 9 you hold diamonds king, clubs 9 and hearts ace. Which cards fit without a special action?
Answer and explanation
Clubs 9 matches rank; hearts ace matches suit. Diamonds king does not fit. Red printing is not the same thing as a matching suit.
Exercise 2: the declaration matters
Spades jack is on top, with clubs declared. You hold spades ace, clubs king and diamonds jack. Which plays are allowed in our study rules?
Position as text
Mau-Mau: jack. Crazy Eights: eight. Switch: ace. UNO: ordinary Wild. Other rules remain different.
Answer and explanation
Clubs king and diamonds jack. Spades ace does not match the active declaration. Our agreement permits another jack and a new declaration; another table might specifically forbid that second jack.
Exercise 3: draw two or pass it on?
A seven has given you a pending draw-two action. You hold another seven and a jack. Can either defend against it?
Answer and explanation
No. This study agreement disallows stacking. Draw two and lose the turn. Ordinary matching is checked again only after the penalty is resolved.
Exercise 4: an eight with two or three players
A, B and C sit in that order. A plays an eight. Who acts next? What changes with only A and B?
Answer and explanation
With three players, C acts because B is skipped. With two, A acts because the only other player, B, is skipped. The rule is identical; the resulting order differs.
Extra exercise: three sevens
For this exercise only: sevens can be forwarded, adding two each. A, B and C play one seven each; D cannot answer. How many does D draw?
Answer and explanation
D draws six: 2 + 2 + 2. Playing afterwards is a separate agreement; here payment ends the turn. In our non-stacking baseline, B’s response would already be illegal.
Extra exercise: tens instead of eights
For this exercise only, tens skip and eights are ordinary. A, B and C sit in that order. A plays a matching ten. Who acts? What if A had played an ordinary eight?
Answer and explanation
After ten, C acts and B is skipped. After eight, B acts. A rank has no fixed special effect outside the agreed ruleset.
Extra exercise: forwarding a skip
Here only, eight on eight forwards a single skip. A plays eight, B answers eight, and C has no eight. A, B, C and D sit in that order. Who acts next?
Answer and explanation
C is skipped once and D acts. This agreement does not accumulate future skipped rounds. Without forwarding, B would already have been skipped and unable to respond.
Extra exercise: declared suit and a jack ban
For this exercise only, jack-on-jack is forbidden. A spades jack is on top with hearts declared. You hold hearts king and hearts jack, with no penalty pending. Which can you play?
Answer and explanation
Hearts king matches the declaration. Hearts jack remains blocked by the explicit jack ban. Our original study baseline instead permits the second jack.
