Claim a Stone in Schotten Totten: Proving the Unbeatable

Claiming is a proof, not a guess

A stone is not yours because your formation looks strong. It is yours the moment it becomes provably unbeatable — when no card the opponent still holds or could still draw would let them build a better formation on their side. The basic rule is in the Schotten Totten rules; this guide is about using it well.

That word provably is the whole game. The engine that resolves a claim doesn't ask whether you're probably ahead; it asks whether the opponent's single best possible formation — assembled from every card you can't yet see — still falls short. If it does, the stone is yours. If even one winning formation remains reachable, the claim is denied. Learning to run that proof in your head is the deepest skill in the game. How rarely each threat comes together is counted in the Schotten Totten odds. How many stones are actually won by proof rather than head to head, and with which formation, is in our Schotten Totten formation statistics.

How to prove a stone

The claim check is a fixed sequence. Run it exactly like the engine does:

1. Can you even claim? It must be your claim step, the stone must be unclaimed, and your side must be full — three cards, or four on a Mud Fight stone. An unfilled side can never be claimed.
2. Read your formation — its rank and its card total. Say your side shows 7-8-9 in mixed colours: a run, total 24.
3. If the opponent's side is also full, just compare. You claim only if you strictly win the head-to-head — and an equal rank and total goes to whoever completed first, so a tie is yours only if you finished your side before they finished theirs.
4. If their side isn't full, build their hidden pool: take all 54 Clan cards, remove every one you can see — both sides of every stone, the whole discard — but not the cards you hold: your hand proves nothing, so they still count. Everything left counts as a card they could still get.
5. List what beats you — any higher rank, or your rank with a higher total. Against a 7-8-9 run: any colour run, any three of a kind or any colour. Another mixed 7-8-9 would only tie, and against a side still incomplete that tie is yours (step 7).
6. Check each threat against the pool. If the cards a threat needs are all still hidden, it lives. If even one is visible on the board, that threat is dead; a card you hold does not kill it.
7. If every threat is dead, claim. If one survives, wait — more cards will be revealed and counted out later. An exact tie counts in your favour, because you completed first.

Ties go to whoever finished first

The tiebreak is a tactic in disguise. When two formations match on rank and total, the stone goes to the side that completed it first — so the order you lay your cards matters as much as the cards themselves.

This has two faces. Against an opponent whose side is already full, a tie is theirs unless you completed before them. But against an opponent who is not yet full, a tie is yours: you're already done, and their best hypothetical formation would only finish later. So racing to complete a strong-but-tieable formation one turn early can flip a coin-flip stone permanently into your column. Every variant of this tiebreak, replayed on a real position, is ruled on by the engine in the Schotten Totten FAQ.

How Mud Fight and Blind-Man's Bluff change the proof

Two tactic cards rewrite the check on a single stone:

• Mud Fight raises that stone to four cards a side — you can't claim until you've placed all four — and the side is judged as one four-card formation: a run or a colour run needs four values in a row, three of a kind needs four cards of one value, a colour needs four cards of one colour, and the sum adds all four. When you build the opponent's best possible side for the proof, complete it to four cards, never three.
• Blind-Man's Bluff makes the stone total-only: formation ranks are ignored entirely, and the claim turns purely on whether your card sum can't be beaten. A colour run carries no weight under Blind-Man's Bluff — only the numbers.

And a subtlety worth knowing: when the engine builds the opponent's best possible formation, it fills their empty slots with Clan cards only. A Joker, Spy or Shield-Bearer that hasn't been played yet never blocks a proof, so you don't have to count the tactic cards still in the deck or in a hand. Every tactic card is covered in the Schotten Totten tactics cards guide.

When to claim — and where to fight

• Proof gets easier late in the game. Early on, few threats are counted out, so few stones are claimable. As the discard and board fill, beating cards vanish and stones fall. Patience here is not passivity — it's waiting for the proof to close.
• Never claim on a feeling. A stone you believe is winning can still hide an unseen colour run. The only claimable stone is one you've counted until no threat is left. Claims are irreversible, and putting off one you can't yet prove costs nothing. Only the Schotten Totten expert variant forces a wait: your claim moves to the start of your next turn, after a full turn of your opponent's. The tactics variant keeps the base-game order.
• Two win conditions run at once: five stones total, or three adjacent. Adjacency is the faster path, so it dictates where to fight — press three neighbours, and on defence contest or claim the middle stone of any threatened trio to break it. How much each condition weighs in practice, measured over games of the AI against itself, is in our Schotten Totten beginner tips.
