No progression beats the edge, and doubling after a loss is the dangerous one

Martingale doubles the stake after every loss. Anti-martingale doubles after every win. Both return 97% of everything staked, because that is fixed by the game. The difference is that one of them can take your whole balance in a single sequence.

Martingale, in numbers

Start at 50, cash out at 2x, double after every loss. Each win recovers everything plus one unit, which is why it feels like it works. The sequence of stakes required to survive a losing run is what kills it.

Loss 1

next stake 100

Loss 3

next stake 400

Loss 5

next stake 1,600

Loss 7

next stake 6,400

Loss 9

next stake 25,600

Cumulative staked by loss 9

over 25,000

At a 2x cash-out you lose about 51.5% of rounds, so seven consecutive losses is roughly a one-in-eighty session and nine is roughly one in 350. Play often enough and it arrives. Your balance or the table maximum stops you before the recovery does.

Anti-martingale, the safer inversion

Double after a win instead, and reset after a loss. You are risking winnings rather than capital, so a losing run cannot compound. Many small losses, occasional larger wins, and the same 97% return as everything else.

It is more survivable, which is a real difference. It is not an edge, which is the part usually left out.

Why neither can work

A staking system decides how much is on each round. The game returns 97% of whatever is staked, round by round, independently. Rearranging the sizes cannot change the average of a fixed percentage, and no arrangement of bet sizes has ever changed the return on a fixed-RTP game.

If you use a progression anyway

• Prefer the anti-martingale direction. It risks winnings rather than capital.
• Set the session amount as a deposit limit before starting, so the sequence cannot run past it.
• Decide the reset point in advance rather than during a losing run.
• Understand you are choosing a variance shape, not improving your position.
