You can get your chips in different monetary denominations. When you hand the dealer your chips, he or she will ask what denomination you want to designate your chips. If you're at a $5 minimum table, you could make them $1 or you could make them $100 (or anywhere in between). Once you've chosen, they'll place a chip on top of the rail, with a marker on top of that to indicate your colored chips' value.[5]
Roulette games have minimum bets, which will be posted on a placard at the table.  Minimum bets work differently for inside bets (specific numbers) and outside bets (everything else).  For outside bets, any bet you make has to be at least the table minimum.  Inside bets can usually be as small as you like, as long as the total of all your inside bets is the table minimum.  For example, with a table minimum of $5, you could put $5 on #14, or $1 each on #14, #27, #8/9, #28/29/30, and #19/20/22/23.  Remember that you can bet inside or outside if you like; there's no requirement to bet both on a given spin.

But the “triggers” that have no effect are like “wait for 5 reds in a row then bet black”.
