As a precautionary measure, PokerStars is no longer offering free online poker to residents in the Washington state.

On Wednesday, the Washington State Gambling Commission announced that several social gaming websites including PokerStars “have proactively made the business decision to deny Washington residents access to their sites.”

The move comes on the heels of a U.S. federal appeals court decision, which ruled social casino games are considered illegal under the existing gambling laws in the State of Washington. Last week, the Ninth Circuit of the U.S. Court of Appeals overturned a district court ruling that junked a 2015 case against Big Fish Games’ then-parent company Churchill Downs Inc.

The lawsuit sought to recover the value of Big Fish Casino virtual chips worth more than $1,000 which the complainant claimed represent “something of value” under the Washington Gambling Law. The virtual chips don’t have monetary value, but they’re needed to play in Big Fish Casino’s suite of games, which include slots, blackjack and roulette. If a player runs out of the chips, he will either need to purchase more or wait until the game offers free chips.
