2way[edit]
The Wrong idea[edit]
The idea is to enter 2 bets, One for winning, one for loosing, i.e. the change for red or black on roulette. ^{[2]}
You enter:
The result will show that you will loose (in the end) in all cases. See below. 
So that's is not the way to win and shows where this calculator is not helping you.
The Right idea[edit]
Now an example which shows how to do it right.
Suppose the winner of the Soccer World Champignons is Brasil (quote: 1.85) or Germany (quote: 2.54). Now you can always win by:
So you enter the following data:

The results is that
So in both cases you win a little money. When you higher the stake by multiplying both stakes with the same number, the profit also increase with the same multiplier. 
3way[edit]
Works exactly the same as the 2way but has one more option a draw as result.
Yankee Calculator[edit]
Please note: Currently the Each Way is not yet implemented.
The yankee is a 4 selection wager consisting of 11 bets:
 6 doubles,
 4 trebles,
 1 fourfold accumulator.
The yankee is rumoured to be named after an American soldier who placed a small bet in the UK and won back hundreds of thousands due to the multiple rollover mechanics at work.
Composition[edit]
Assume your bets consists on the results of 4 games 1, 2, 3 and 4, then the individual bets are:
Yankee Composition Parts  

Part  Selections (14)  Number of Bets 
Double  12, 13, 14, 23, 24, 34  6 
Treble  123, 124, 134, 234  4 
FourFold  1234  1 
Total  11 
Usage[edit]
The input fields for the odds use the Decimal format and not American or Fractions. (See for explanation how to convert: https://www.timeform.com/betting/basics/oddsconversion).
Fill al the 4 requested odds and enter the Stake per bet.
Since a Yankee consists on 11 bets, a € 1.00 equals € 11.00 in total.
After filling the Stake per bet all calculations will be made.
