Sports Prediction Rules

Each prediction is tied to a specific market on a sporting event — such as the winner of a matchup, a spread, a total, or a prop. Your pick is the side or outcome you select before the market locks. You never enter a score.

• Markets lock at the scheduled start time shown on the game. Picks cannot be changed after lock.
• A pick is only active once your buy-in is held in escrow; an unconfirmed pick is not an entry.
• The market terms displayed when you confirm govern settlement, even if lines later change.

When you place a bet, the corresponding SHK is placed in escrow. Shake holds these buy-ins for all participants so the pot is fully funded before the event begins.

• Held SHK is shown as “in escrow” and is unavailable for other bets until the current one settles.
• When the event is final, Auto-Payout instantly distributes the pot to the winning side based on the contest format.
• If a contest never reaches a valid result, held buy-ins are returned to participants (Sections 4 and 5).

Outcomes are determined automatically using official results surfaced through Shake’s sports data provider. In this prototype the provider is a mock implementation; in production it would be backed by an official feed. Either way, users never enter scores.

• Final, official scores take priority over any in-app live or provisional figures.
• Where multiple sources conflict, the official league result controls.
• Statistical corrections issued after settlement are handled under Section 7.

A push occurs when the result lands exactly on the line so no side wins. A void occurs when a market cannot be fairly settled — for example, a prop where the athlete does not participate.

For pushes and voids, Shake returns the held buy-ins to each participant via Auto-Payout, with no winner or loser recorded for that market.

If an event is postponed and rescheduled within the contest window, the prediction generally carries over and settles on the official result. If an event is cancelled or not rescheduled within a reasonable period, the related markets are voided and buy-ins are returned.

Group bets and brackets settle on a points or elimination basis depending on the format chosen when created. The winning side defined by each format receives the pot via Auto-Payout.

• Pick'em — one point per correct matchup; the highest score takes the pot, ties split evenly.
• Survivor — pick one winner each round; a single wrong pick eliminates you; the last standing wins.
• Props — score points across listed player and team props; totals are summed at settlement.
• Bracket — earn escalating points for correct picks each round; the highest cumulative score wins, and the top finishers split the pot.

If you believe a contest settled incorrectly, you may flag it for review within the dispute window. Where an official correction changes a result after Auto-Payout, Shake may re-settle the affected contest and adjust SHK balances accordingly. Decisions are final once the review window closes.
