Uranium Rush is a 1955 board game published by Gardner & Co. The game is educator approved on the basis that it connects the Uranium Rush of 1950 with the famed Gold Rush and for it's use of a Geiger Counter mechanic for prospecting of Uranium.
How is it played?
All the players begin with $15,000. When it is their turn, a player spins the arrow on the wheel shown left of here. The area the arrow points to (purple mountains, green hill country, or sandy desert) determines where on the board the player can prospect. To stake a claim, a claim marking stake must be purchased from the government bank for $1,000.
At this point the player stakes a claim in any one of the mines in his/her area. Either the claim can be auctioned off or the player can test the claim. This is done by touching the base of the Geiger Counter to the player's master plug and touching the tip of the GM to the small metal circle around the mine (each side of the board has one master plug). If the GM lights and buzzes, uranium has been discovered and the lucky prospector receives $50,000 from the government bank! Next, the player takes a government instruction card and follows the directions. The turn is then passed on to the next person. When all the claims have been staked, the player with the most money wins.
