Top Fog Tech
The casino’s key trick was a special glycol fog tech so you could only see well up to your nose. This smart air trick let the staff see all but made it hard for players to know where they were, forcing them to use lights above to move around.
Clever Club Plan
A neat seven-level club rule set who could come in and play, while tricky shadow books kept rules that helped the house win more. This smooth plan let the casino run without any problems while keeping it safe from curious eyes.
Mark Left By the House
The club’s tricks taught at least seven other secret spots around the area until 1932 when cops found trick dice. Marcus Thane’s vanishing in 1933 made the place even more of a story, leaving behind tricks of design and running hidden fun spots.
The Fog & Dagger’s slick ways to hide and twist the odds marked a big chapter in hidden casino tales.
How Hidden Fun Began
The Start of Secret Bets in 1920s Seattle
The Start of Hidden Play
In 1924, Marcus Thane, a bar man with big ideas, started what the old books say was the town’s first hidden casino.
Under his bar, The Rusty Anchor, Thane brought in sneaky ways to keep the fun hidden that would shape how casinos kept safe for years.
Clever Hiding Ways
The found building plans show Thane’s smart safety setup, with fog machines and angled glass. This setup kept the fun hidden well from the cops.
People would get in through a hidden meat storage door, then walk through the Thane Maze – a mix of paths made to confuse unwanted guests.
The Northwest Game Changes

Thane’s sneaky ways spread fast in the Northwest betting world. From 1925 to 1931, at least seven hidden clubs took on his methods, making a loop of secret fun spots.
When cops found fixed dice and marked cards in 1932, it showed Thane’s deep tricks. Old money books say his hidden place made over $2 million before he disappeared in 1933.
