In Spread-Limit Texas Hold'em games, you're allowed to bet any amount, within a given range, during a betting round. So in a $1 to $5 game you're allowed to bet $1, $2, $3, $4, or $5.
About the only place you find Spread-Limit Hold'em is playing at other people's kitchen-table home games. Professional card houses dealing a Spread-Limit game are very rare, indeed, tending to happen only in places sitting in Poker backwaters.
Typically in Spread-Limit, your raise must be at least equal in size to the bet in front of you. If someone bets $3 in a $1 to $5 game, and you want to raise, you can raise by $3, $4, or $5 only. Don't be afraid to ask the dealer what the betting rules are if you come across a Spread-Limit game.
Usually, the minimum buy-in (the amount you need to start playing the game) in a Spread-Limit game is ten times the lowest betting amount — so $10 in a $1 to $5 game. There is no maximum.
