Battle Line

Each turn you do exactly two things: play one card from your hand of seven onto one of three open slots in front of one of the nine flag positions, then draw one card from either the Troop deck (numbers 1-10 in six colors) or the small Tactics deck. The Troop play is the entire physical action — the satisfying click is committing a number to a flag and watching your opponent recalculate.

The board is nine flags arrayed between two players. To win a flag you build a 3-card 'formation' on your side that beats your opponent's — formation rankings are exactly poker-derived: Wedge (straight flush) > Phalanx (three of a kind) > Battalion (flush) > Skirmish Line (straight) > Host (anything else, sum of pips). You may claim a flag at the start of your turn only when you can prove deductively that your opponent cannot complete a higher formation given the cards remaining in the unseen draw and discard piles. Tactics cards (10 total in the deck) bend the rules — Leaders are wilds, Companion Cavalry is an automatic 8, Fog cancels formation comparison and uses sum, Mud expands all formations to 4 cards. Tactics play is rate-limited: you may never have played more than one more Tactics card than your opponent. Win by claiming any 5 of 9 flags or any 3 adjacent flags — the second condition forces positional attention to the center.

Every turn poses three nested questions: which flag to commit this card to, whether to commit at all (sometimes a card is too valuable to spend on a half-formation), and whether to draw Troop (more numbers) or Tactics (more rule-bending). The signature tension is information accounting — knowing precisely which 1-10 cards in each color have been played or discarded, because the game is won by Sherlock-style proof that no formation can beat yours. Tactics cards introduce a wild-card layer that can flip a flag but invite retaliation, and the 'no claim until provable' rule makes endgame closeouts excruciatingly tight.

Card counting and combinatorial deduction dominate — strong players track every played and discarded card by color and value, computing exact odds that an opponent's incomplete formation can still beat theirs. Risk-tolerance and tempo are the second axis: when to commit a 9 of red to a flag versus hold it for a stronger build elsewhere. Bluff and opponent-reading matter at intermediate levels but evaporate at high play because the game is fundamentally a deduction puzzle with hidden draws. Knizia himself has emphasized that Battle Line rewards proof, not gut.

A two-player poker-meets-deduction duel dressed as ancient warfare: build the better battle line, claim flags by mathematical proof, occasionally summon Alexander to break the tie.
