What we suggest you do if you want to win at the casino with little money is, not in any specific order:

1
Find games with a high RTP.
2
Play casino games with the best payouts.
3
Learn about the games you are playing.
4
Take advantage of bonuses.
5
Know when to walk away.
Most slot machines in land-based casinos still use a sensor to determine how many coins or bills are being inserted. By interrupting these sensors with a pocket laser light you can make the machine think you're inserting coins or bills while you aren't.
