Thinking

  • Check visible cards, including played and discarded to determine the focus and the meaning of a clue.
    • e.g. you are given a     clue. You see 2 was played and the second 2 is in another hand. Therefore the clue means "   s which are not red".
    • e.g. you are given a     clue that marks only your chop. You see no    s have been discarded and no    s on the chop of the players next to you. Therefore the clue means "this     is playable".

Cluing

  • Don't mark trash cards
  • Save unique cards as the first priority.
    • Look ahead for unique cards on chop. Sometimes more than one player must help to save consecutive unique cards.
  • With few clue tokens, work out which players need them.
  • Consider how the receiver can interpret your clue.

Discarding

  • Trust your teammates to manage your cards.
  • When there is nothing urgent to clue, don't be afraid to discard! Discarding is often the best move for the team.

Playing

  • When multiple cards are marked, determine the focused card. Each clue only has one focused card.
  • Logically playable cards are marked at the earliest opportunity, so the leftmost card is assumed to be the focus of play clues (where no other cards are known to be playable).

Triggering the final round

  • Sometimes a specific player should draw the last card to maximise the score.
  • Giving empty clues (e.g. "you have no red card") can help to manage which player draws last card.

  • Alice and Bob both give empty clues e.g. "to Cathy: you have no white card".
  • Cathy plays 4 and draws the last card.
  • Alice plays 5.
  • Bob discards.
  • Cathy plays 5.

Skip / steal

  • When a player gives a clue that could have been given by one of the skipped players, it means the skipped players have a better move than to give the clue that was used to skip.
  • Skipping should be avoided unless there is a good reason.

  • If Alice discarded instead, Bob would have clued Alice red     to finesse 1 and 2.

Potential reasons for skipping players:

  • Clue-giver is locked i.e. all cards are marked without any immediate plays.
  • Gain tempo to play e.g. skipped player(s) all have playable cards.
  • Gain tempo to clue e.g. skipped player(s) must give a fix clue.
  • Avoid a bad clue e.g. mark cards with good touch.
  • Ensure a good clue e.g. mark cards with good touch.
  • Cause a discard e.g. of a playable card so that its copy can be marked with good touch, or of trash.
  • Avoid a discard e.g. a double discard, or of nice-to-have (non-unique) cards.

Cathy 🡲
  • Alice skips Bob to give Cathy a blue     clue because Bob has let let 2 reach chop and does not want to mark it because he might hold a copy.

Additional interpretation

An additional finesse convention is that skipped player(s) cannot discard.

  • i.e. Alice can clue Cathy only if Bob has a play or should give another clue.
  • If a skipped player has no marked playable cards and no good clue to give, they can blind play their newest, unmarked card.
  • A clue-giver who causes unmarked play(s) purely from a skip is responsible for any misinterpretation.
Example 1: lie
* Alice skips Bob to give Cathy a     clue.

Bob 🡲

Cathy 🡲
  • Bob has no clue to give and no known play, so he blind plays his newest unmarked card.
  • In this convention, 1 does not connect to    , so Cathy interprets as a bluff and her     is not playable.
  • This is a lie because 3 is playable.
  • Instead, Alice should have discarded and allowed Bob to clue Cathy so that she knows her 3 is playable.
Example 2: bluff
* Alice to Cathy: this card is red    .

Cathy 🡲
  • Cathy now knows her marked card 3 is playable.
  • Bob does not see the connecting 2, so assumes he has to play it now.
  • Bob does not have a marked card that could be 2, so Bob blind plays his newest unmarked card.
  • 1 successfully plays and the bluff is revealed.
  • Before Bob played, Cathy thought her marked card was 2.
  • After Bob plays, Cathy knows her marked card is any valuable red (3, 4 or 5).
Example 3: unambiguous skip play
* Alice skips Bob to give Cathy a     clue.

Cathy 🡲
  • Bob has no clue to give and no known play, so he blind plays his newest unmarked card.
  • 1 does not connect to    , so Cathy interprets Bob's move as a skip play and plays 1.

2 Player strategy

Basic

  1. Marked cards are not discarded.
  2. Unique cards are saved.
  3. Saves are given as late as possible.
  4. Play clue focus is the leftmost card.
  5. All known playable cards are played before discarding (including 5s with flamboyants).
  6. Marked trash cards are corrected.

Intermediate

  1. Playable first copies are clued.
  2. Playable cards marked with both colour and number will play first.
  3. Last clue tokens is only used to mark a unique or playable chop.
  4. Off-chop saves for consecutive unique cards.
  5. Double discards can be avoided with a stall clue.
    • empty clue
    • splash that marks no new cards
  6. Cards are played in clued order.
  7. Plays that lead to other plays are prioritised.
  8. Lower ranked cards are prioritised.
  9. Unique cards are splashed.
  10. Black Powder: 1 is only marked on chop unless all other 1s (or 2) are already played.

Advanced

  1. Number clues that mark a non-unique chop are play clues.
    • e.g. with no    s discarded, play the left    .
  2. Black Powder:    s are marked with a playable 5 on chop. In a following turn the     to the left of 5 is marked with colour to play 5.
  3. Before playing, a connecting card on chop can be marked.
  4. Flamboyants: consider not locking a hand with a 5 save.
  5. Avalanche: any card can be multicolor.
    • i.e. wait for negative multicolor on a 5 before playing as 5.
  6. Scream discard = save the chop card (and move chop one slot to the left).
  7. 1-away from playable cards are splashed.
  8. Trash cards are discarded before being splashed.
  9. Already-marked trash cards are splashed.
  10. An early game     may be discarded.
  11. Black Powder: avoid discarding after an early game 1 or 5 save.
    • To allow consecutive 1 and colour 5 saves.

Early game

  1. At least clue tokens are used before the first discard.
  2. Black Powder: 5 is marked first if it is the leftmost    .
  3.    s are marked next.
    • Black Powder: 4 is marked if there are no other    s.
  4.    s are marked next.
    • With multiple marked unknown    s in your hand, consider first playing your    s or marking    s individually with colour.

Alternative strategy

  1. Any card may be saved, including non-unique cards.
  2. Cards marked with a number are only splashed with colour:
    1. If a previously unmarked card is playable.
    2. As a stall clue.

Advanced moves

Discard clue

  • A discard clue marks known trash cards to prevent an unwanted discard (or misfire).

Discarded: 34

  • 3 and 4 need to be saved.
  • If Alice gives a     clue, 4 might be discarded.
  • Alice gives a     clue so that Bob discards 1 and 1 before his chop card.

Play refusal

  • Instead of playing, a player clues or discards their chop.
  • The next player must consider if the play refusal is waiting for a potential reverse or if there are unique card(s) to save.

Positional Discard

  • In the endgame when you can see all remaining playable cards, you can use a positional discard to communicate the slot position in another hand.
  • Typically used with clue tokens or where trash cards make it awkward to clue the target.

  • Bob has been given a play clue and does not see a playable card in any hand, so Bob blind plays his draw card.
  • 1 successfully plays.
  • Cathy sees that Bob has 2 in front of 4 but 3 is missing, so Cathy knows she must play 3 at the correct moment.
  • Cathy discards, Alice discards and Bob blind plays his 2nd slot 2.

  • Bob sees a playable 1 in Cathy's hand, layered behind other playable cards 2 and 2.
  • Bob discards and Cathy blind plays for 1. 2 successfully plays.
  • Cathy knows this cannot be a bluff because Bob would not discard unless he sees a playable 1 in Cathy's hand.
  • So Cathy knows she is promised 1 and keeps playing each slot from left to right until her 1 is played.

  • If the following two players both have a playable finesse position, you may be able to perform a finesse bluff.
  • The first blind play connects to the target.
  • The second blind play does not connect to the target.

  • Cathy must act now to prevent a misfire of 2.
  • Cathy blind plays 1.
  • With two blind plays, Donald now knows his     is not 2 or 2 and this was a double bluff.

Promise bluff

This move only applies to 1-away-from-playable bluff interpretations.

  • Promise bluffs give more information than regular bluffs, as they promise the necessary connecting cards to make the clued bluff target 1-away-from-playable. These connecting cards must be either marked or unmarked in finesse position.

  • Bob must act now to prevent a misfire of 4.
  • Bob blind plays 2 and the bluff is revealed.
  • Cathy sees Bob's 3 was in finesse position behind 2, so now knows that her marked card is either 4 or 3.
  • Bob knows that for the bluff target to be a valid 1-away-from playable, he is also promised 3 in his slot 2.

Empty clue double save

  • With not enough clue tokens or turns to save consecutive unique cards, an empty clue can save two chop cards.

Discarded: 34

  • 3 and 4 need to be saved.
  • If Alice gives a     clue, 4 might be discarded.
  • A     clue will cause a misfire of 2.
  • Alice gives an empty clue (e.g.     or     or white    ).
  • Bob knows that if Alice played her 2, so this empty clue must mean something.
  • Bob does not have a playable card and knows Alice could have saved his chop card with this clue token.
  • Bob interprets this as 'do not discard two chop cards' and discards 2.
