Pot Odds
Risk against reward, worked out in your head against a clock. SIG teaches its new traders poker for a reason: pricing a call is the same shape as pricing anything else, and the frequencies that make a bluff break even are the indifference conditions behind any two sided market. No cards, no money, just the arithmetic.
More speed drills
The same two minutes of arithmetic without the poker framing is in Mental Maths, and every ranked game feeds the overall leaderboard.
A maths drill, not a gambling product. Nothing here is played for money, there is nothing to stake and nothing to win.
