Hi guys,just a few questions that i cant figure out regarding slot machines in Australia
1) In australia we have 1c,2c,5c and $1 5 reel video slots. Most are multiline machines 1-5-10-15-20-25 lines etc with coin bet function of course. Whats the best way to play these machines"? Do you suggest just playing the 1 line or is it better to play 5 10 15 20 or 25 line. Oviously on a 5c machine if you play 25 line each bet would be $1.25 as i seem to go through to much money.

1) how much do you play a machine before you figure out its cold or not a good payer, i use $20,so should i just use $10 and use 1 line or better to use 5 lines or more?

Any info would be great,im not after a huge jackpot just alitle bit extra here n there.
