"Betsize" is a word that refers to the total amount wagered by a player in a slot. It can be levied in virtual currency units, like the Chips used at Jackpot.de, as well as real money at a number of other casinos. The betsize is determined by the bet-per-round and may vary for each and every slot. A higher wager increases your possible winnings, but naturally also your risk. It is important for players to keep their budget in mind and choose a betsize that they are comfortable with and can afford to lose.
