Rules

Sign in, pick an open pool, and confirm the 18+ and terms statements — your wallet signs that confirmation once per terms version. Pay the entry price for the tier. Before an entry is accepted, your wallet is checked against published sanctions lists; every wallet due a prize is checked again before payment. You then set seven battles on one 3-minute clock, which starts when you place your first point: in an easy pool each battle splits 100 points across five stats; in a hard pool you place 700 points anywhere across the seven battles, every stat between 0 and 700, and the pool's page says which rule it plays. Your battles are encrypted on your device before any payment moves. One entry per wallet per pool; there is no limit across pools. The keys that run the service — the admin, the keeper, the entry signer and the settlement signer — can never enter. A pool holds 8, 16, 32 or 64 players and runs with at least its minimum field (see the field-size rule). Decisions are final: a submitted entry cannot be changed or withdrawn (see the refund rule for pools that never reach their minimum field).

Seven entry prices (tiers) are configured. A tier must be switched on by the operator before pools open in it; at launch only the smallest tier is on. In each tier, pools come in four sizes on each board, and one pool of each size and board is open at a time; a new one opens 5 minutes after the previous one has paid out or closed.

Every pool pays fixed prizes to its highest places, from a table set by the pool’s size and entry price — never by how many players entered. The prizes are moved into the pool’s own prize vault from the prize treasury before entries open, and they are the same whatever size the field turns out to be. The tables below give every prize, by pool size and entry price. Players tied on a rank share the prizes of the places they occupy (see ties). Prizes are paid automatically when results are committed; there is no claim step.

Every player faces the identical field: your battle 1 is compared against every other entry’s battle 1, and so on for all seven. A battle is won by taking three or more of its five stats; if neither side takes three, it is a draw worth half a win to each. Rankings are ordered by total battles won (a draw counts half), then by total stats won across every comparison. The ordering is fully deterministic: the same sealed battles always produce the same ranking.

One clock runs for the whole board. It starts when you place your first point. When you submit, or when the clock ends, any points you have not placed are spread evenly across the stats of every battle you have not locked in: in an easy pool each battle spreads its own unplaced points across its five stats, so a battle you never touch is entered as 20 points in each; in a hard pool the board’s unplaced points are spread across every stat of every unlocked battle. Against any allocation that concentrates points on three stats, an even split loses that battle three stats to two, every time — so it never beats a player who is thinking. Nothing is decided at random: the spread is fixed and published, and leaving points unplaced is a decision like any other. After an early submit you see the result and can go back while time remains; when the clock ends, the board is final.

Players are ranked by battles won, then by total stats won. Players who remain equal on both share a rank. Entry order plays no part in ranking or in deciding who is paid. It determines only where an indivisible remainder of a few lamports falls when a prize cannot be divided exactly. Your entry number is recorded when you enter and is visible to you before the pool closes. No random process is used at any stage of ranking or payment. Players who share a rank share equally the prizes of the places they occupy together: two players tied for 3rd are each paid half of the 3rd and 4th prizes combined. A tie that reaches past the last paid place is treated the same way — the prizes of the paid places it covers are divided equally between everyone in the tie, so each of them is paid a share even though some of the places they occupy pay nothing. Nobody ranked below the last paid place, and outside such a tie, is paid. If a flag is upheld, the withheld prize stays in the pool’s prize vault and can only ever be paid to other players of the same pool; it never goes to the operator. Any indivisible remainder goes to the eligible player with the lowest entry number. A prize is always paid to a player. It is never returned to us. Where more than one player shares the rank a prize passes to, we identify that group. The published rule is that they share equally, with any remainder going to the lowest entry number. The results bundle we publish after every pool lets anyone check that we identified the group correctly.

Randomness from a recent slot hash, mixed with your entry’s position in the pool, the pool and your wallet’s key, decides ONE thing: which character class artwork your pass shows. Class is cosmetic. It does not affect any stat, any battle, any score, any rank, or any prize — nothing in the scoring path reads it. Scoring and prizes depend only on the sealed battles every player submitted. Every class draw is replayable from published on-chain data.

Your battles are encrypted on your device before they are submitted. The key that can decrypt them is generated and held by our systems, locked against export, and is not released until the pool closes and no further entry is possible. Until that moment no battle in the pool can be read, by us or by anyone else. A hash of your battles is recorded on-chain at entry. When the pool runs, the pool secret is published on-chain: at that moment everyone’s battles become readable and checkable against the hashes committed at entry, and anyone can re-run the scoring.

A pool holds 8, 16, 32 or 64 players, and each size has its own minimum field: 5 players in a pool of 8, 10 players in a pool of 16, 20 players in a pool of 32, 40 players in a pool of 64. Entries stay open for up to 12 hours from the moment the pool opens. The pool runs the moment it is full, or when the 12 hours end with at least its minimum field. Nobody decides when a pool runs; the number of players entered and the clock do, and anyone can trigger the start once the clock has ended. The prizes are the same whatever the field size.

A pool whose clock runs out with fewer players than its minimum field — 12 hours after it opened — refunds every entry in full and closes. Your entry payment is held by the program until the pool runs, so the refund never depends on the operator. Anyone can trigger the refund once the deadline passes; no one’s permission is needed.

Each size of pool runs one pool at a time on each board and at each price. A pool opens when the prize treasury holds its full prize pool, the previous pool of the same size, board and price has paid out or closed, and 5 minutes have passed since. Prize tables are fixed per size and price, and are funded before entries open.

Every number a player is paid is recomputable by that player. The Verify page decrypts the published battles with the revealed pool secret, re-runs the same scoring engine in your browser, rebuilds the results tree, and compares it against what was committed on-chain. Nothing on that page trusts the operator.

Blotto Cup is available everywhere except the territories listed below. Where the service cannot determine your location, entry is not available.

Blotto Cup is for adults 18 and older. Entering requires a signed confirmation of age and acceptance of the terms, recorded per wallet and per terms version.

Entries are final and outcomes depend on how every player in the pool allocated. Enter only with funds you can afford to spend, set your own limits before you start, and step away when it stops being enjoyable.

Five published signals are computed over data every player can see once a pool is revealed: (1) placement patterns — reuse of the same split, uniform round numbers; (2) timing — how the time on the clock was actually spent, battle by battle; (3) duplicate or near-duplicate battle sets across entries; (4) the same device behind multiple entries in one pool; (5) a score far outside the field’s distribution. These signals are computed for every pool. Every decision and the criterion cited are recorded in a log anyone can read. Nothing is flagged automatically: a flag is a decision taken by a person that an entry meets one of the criteria above, and a flag never decides anything by itself — it only sends the entry to the signed review process below.

When a pool closes, results are published and the pool enters resolving. Resolving lasts up to 12 hours. During resolving we check every wallet due a prize against published sanctions lists, as we are required to. Where an entry has been flagged against the integrity criteria published above, a person decides that flag against those criteria. A flagged prize is held by the program: it is not paid to us and it is not paid to anyone else while the review runs. If no decision is made within 12 hours, the flag is cleared and the prize is paid. Separately, and as a safeguard against our own failure, the program allows anyone at all to release a held prize to the player it belongs to after seven days, without our involvement. You may challenge a decision through our complaints route, and we will tell you which criterion was cited. Every decision and the criterion cited are recorded. If a challenge succeeds after the prize has been paid to another player, we pay you the full prize ourselves and do not seek to recover a prize already paid.
