Small Budget Progressions

Some small-budget progressions for even-money bets:

Must make a parlay: 1-1-1-2-2-3-4-5-7, 9 chances to make a parlay, risking only 26 units.
(Win / Loss, Win / Loss, Win / Loss = Lose / Lose / Lose )

Must only win the same bet twice (no parlay): 1-1-2-3-4-6-9, 7 chances to win the same bet twice, risking only 26 units.
(Win / Loss, Win / Loss, Win / Loss = Even / Even / Even )
