Rules

Minimum age to place a sports wager

18 · WSGC's sports-wagering rules list anyone under 18 as a prohibited participant; this is lower than the general tribal-casino gaming-floor age because sports wagering has its own minimum age.[3]

Wagering on college sports allowed at all

Yes · Wagers on out-of-state collegiate events are allowed, but wagers on Washington collegiate institutions' own events or teams, and on any collegiate event taking place in Washington, are prohibited.[3]

Wagering on in-state college teams allowed

No · Wagers on Washington collegiate institutions' own events or teams, and on any collegiate event taking place in Washington, are prohibited.[3],[4]

Credit cards may be used to fund accounts

No · A tribal sports-wagering compact's standard list of ways to fund a player account (cash, cash equivalents, cashiered deposits, promotional credit, winnings, and agency-approved adjustments) does not include credit cards.[4]?Drawn from one tribe's compact appendix (Chehalis); the list's final catch-all for other agency-approved funding methods is open-ended.

Esports wagering allowed

Yes · HB 2638's statutory "sports wagering" definition explicitly lists "[a]n electronic sports or esports competition or event."[1]

New online accounts must be created in person

Yes · To open a sports-wagering player account, a patron must register in person at the tribal gaming facility and provide identifying information verified against a government-issued photo ID.[4]

Statutory cap on number of online sportsbook licenses/skins (omit if uncapped)

0 · No commercial/non-tribal online sportsbook license category exists; all sports wagering is under tribal compacts.[1]

Online sports wagering available statewide (not tethered to premises)

No · Mobile wagering is geofenced to tribal casino premises only, not available statewide.[1]

Operators must use official league data for some bets

No · Washington's tribal sports-wagering compacts do not require operators to use official league data for any category of bet; they only set licensing requirements for vendors that choose to supply such data.[4]?Drawn from one tribe's compact appendix (Chehalis); Washington's compacts follow a standardized template but are negotiated and amended tribe by tribe.

Summary of prop-bet restrictions (e.g. no in-game player props)

No restriction applies by bet type; wagers are instead restricted by subject. Any event sponsored by a Washington collegiate institution, any collegiate event held in Washington, and minor league sports are all off the board regardless of bet type, including wagers on a "portion" of an event.[4],[3]?Drawn from one tribe's compact appendix (Chehalis); Washington's compacts follow a standardized template but are negotiated and amended tribe by tribe.

   Fetched directly and parsed with pdftotext -layout. Effective/approved date confirmed as March 25, 2020. Corrects an earlier inference that esports was excluded from the statutory "sports wagering" definition -- the bill text itself lists "[a]n electronic sports or esports competition or event" (Sec. 11(1)(a)(iv)) and separately defines "electronic or esports event" (Sec. 11(2)); it also excludes horse racing and minor league sports from "sports wagering."

   This appendix is a scanned, image-only PDF; WebFetch could not extract its text, so it was downloaded and OCR'd (pdftoppm + tesseract) for this file. Confirms in-person account registration; an exclusive list of account-funding methods that does not include credit cards (cash, cash equivalents, cashiered deposits, promotional credit, winnings, agency- approved adjustments, or "any other means approved by" both gaming agencies); a licensing category (not a mandate) for vendors supplying "official data" for sports wagering; and subject-based (not bet-type-based) restrictions on Washington-collegiate-institution events and minor league sports. Used as representative of the standardized sports-wagering appendix template across WA tribal compacts, since this file could not OCR other tribes' versions; compacts are negotiated and amended individually, so provisions can vary by tribe.
