Unfortunately, if you play craps the conventional way, you have to get very lucky pressing bets to win a lot of money, or you have to start out making big bets to win a lot of money.
There isn't much chance for a low roller to make a lot of money unless they get lucky on the "exotic" bets -- which not every casino has.
Here are two strategies for betting a small amount of money but gives you the opportunity to win a lot of money with a small upfront cash cost at craps.
I'm going to suggest a low risk, high return strategy:
Bet the passline without odds (odds don't make you win) + a "feature bet" or "exotic bet" (Firebet or small, tall, all) for no more than your passline bet.
EXAMPLE #1 FIRE BET TABLE
As an example, you are at a $25 table. Bet $25 on the pass with $10 on the Fire. ($10 Fire is the maximum bet I know of.)
Your maximum exposure is $35.
If you make one pass (and a winner 7, or winner 11 on the come out is included), your possible loss shrinks to $10.
If two passes are made (come out winners included) you have a profit of $15.
If more passes are made you will have more profits without any additional exposure. And if you hit 4, 5, or 6 Fire Bet points you make much bigger money.
EXAMPLE #2 SMALL, TALL, ALL TABLE
As an example, you are at a $15 minimum table. (Bellagio has this.) Bet $15 pass with $5 on each of the small, tall, all bets. Total exposure is $30.
This is a little trickier because a winner 7 on the come out pays you $15 but you lose your $15 STA bets. But if you avoid the 7 for as few as ten rolls, even if you fail to make even one pass, you will win 5X35 + 5X35 + 5X175 = $1,225.
