Bonus offers are casino specific, not depending on what kind of computer you’re using. One thing you need to check pertaining to bonuses is if the ones being offered can be cleared playing blackjack. Most online bonuses are for slots, not for blackjack play. The ones that let you play blackjack usually have stricter clearing requirements.
Here’s an example. A regular bonus may require a 25 times playthrough on the slot machines before you can take any money out. A playthrough is how many times you have to bet your deposit and bonus amount. If you deposit $100 and get a $100 bonus with a 25 times playthrough, you have to place bets adding up to $5,000 before cashing out. $100 + $100 X 25. If you play blackjack you may have to play up to 10 times as much before cashing out.
The only way to know for sure is to read the bonus conditions prior to making a deposit. BEFORE making a deposit is the time to learn about any possible issues. Most players find a good online casino and a great looking bonus offer and want to jump in and start playing immediately. Take the extra five minutes up front. It may save you a great deal of grief and complications later.
