Different Kinds of Online Slots Tournaments
There are plenty of different tournaments that suit different UK gamer preferences. Here’s a breakdown of some popular tournament types:
- Free/freeroll slots tournaments: These tournaments allow you to play for free with a chance to win prizes. A lot of players find that free slots tournaments with no deposit are a good way to get started with tournaments if you’re new, but don’t expect to be cashing out huge amounts as the prize pools in no deposit casino games won’t be as big as those for the paid tournaments.
- Real money/buy-in tournaments: These tournaments require a buy-in fee, but often offer larger prize pools for players with winning combinations. The amount of money you have to pay to play will vary depending on the casino. Usually, the bigger the prize pool is, the higher the buy-in will be for players who want to take part.
- Scheduled tournaments: Scheduled tournaments occur at specific times throughout the day or week. These work well for people with a busy schedule as you can plan to take part in the tournament in advance and plan your day around the tournament. However, you do have to be careful not to miss it!
- Reloader tournaments: These tournaments reward players who make additional deposits during a tournament period. For these tournaments, you may have paid a deposit to take part, but you’ll also have the chance to make further deposits as the tournament continues, and you’ll get some sort of bonus as a reward like free spins.
- Prize-based tournaments: If you want to win some fun prizes, these are the tournaments that you should try out. Prizes will normally be given out to people for winning and it can include things like free spins or bonus funds that you can use throughout the tournament, or for other games on the casino’s website.
- One-shot tournaments: For those players who are feeling lucky, you might want to try out a one-shot tournament. With these tournaments, you get just one chance to hit the jackpot.!
- Other tournaments: Many casinos offer unique tournament formats, such as knockout tournaments or leaderboard races with ongoing rewards. Suppose you are a new player and want to try out different tournaments to figure out what suits your playing style most. In that case, we’d recommend looking at different casinos for other tournaments as they will vary from casino to casino.
- Survivor slots tournaments: It really is survival of the fittest with Survivor Tournaments as these games will eliminate players at set intervals based on their ranking. This means you have to be at your best the entire time if you want to be the last player standing and claim the top prize.
Best Slot Tournament Tips
Here are some valuable tips to help you climb the leaderboard and maximise your chance to win some money in your next tournament:
- Familiarise yourself with the scoring system, time limits, and eligibility criteria before joining a tournament.
- Select tournaments with games you enjoy and prize pools that match your risk tolerance.
- If the tournament has a time limit, plan your spins strategically to maximise your points within the timeframe.
- In tournaments that award points based on total bet amount, prioritise bets that offer a good return for your investment.
- Highly volatile slots offer the potential for big wins but also come with a higher risk of losing your money. Choose a volatility level that suits your playing style and the tournament format.
- If you experience a losing streak, don’t try to win it all back by increasing your bets excessively. Don’t chase the losses. Maybe take a break instead to regroup.
- Remember, tournaments are primarily for entertainment. Enjoy the competitive atmosphere and the chance to try new games without breaking the bank.
