Made a simulation in Excel (5000 games of cyberace), and the odds for getting a total of 10 or above are 3,56.
There are 3 rounds of numbers being rolled for each color (blue and red). All I did in Excel was rolling 3 numbers randomly between 1 and 4 (3 numbers representing the blue side and another 3 representing the red side). Sum the 3 outcomes for each color, and then, using the "if" formula, counted how many times sum 10 or more came in at least one side.
The results were: 1405 wins in 5000 tries = 28,1% probability = 3,56 fair odd
Betfair pays 8 for getting a "Ten". Thinking this was a valuable move (betting always on "Ten"), decided to play it in Fun mode.
Starting with a bankroll of 1000€ play money, ended my experience with 300€ play money... (I have been doing this experience, one entire morning... ), always betting 5€ play money in "Ten"...!
If i lost play money doing this and the odds indicated this was a value bet, so something is wrong in arcade games...!!
