An important way to extend your bankroll is to manage it properly even before you start spinning those reels. Bankroll management is both a science and an art, and it takes some practise before you get a good system in place.
Start by deciding your budget for a single video slot. If possible, you shouldn't dedicate your entire bankroll to just one slot. Instead, try spreading it around three or more games. Look for games with different game mechanics, such as clusters, Megaways or progressive jackpots. These will provide varied entertainment and different ways to enjoy your bankroll.
If you're stuck choosing your games, search by game type or just pick random ones from the casino's hot or latest picks.
Once you have lined up your slots, check the minimum bet value for each and try to allocate at least 50 spins per slot. If this is not possible, consider switching slots. You will find that many casino slot tips suggest playing a minimum of 50 spins, with many suggesting minimums of 100. This number should provide you with an opportunity to trigger one or more bonus features which could help extend your bankroll.
With your games selected and your budget allocated, you're ready to start playing. At this point, the most important slot machine tip is stick to your choices. Once you have exhausted the budget on one slot move to the next and when your bankroll has been depleted stop playing. Do not be tempted to continue playing, and certainly do not try to make up for any losses.
