Whether you’re playing at a land-based or an online casino, the key to winning at slots is to have a budget and stick to it. Set aside how much you’re willing to spend and decide how fast you want to play. You can also try to choose a low-volatility slot machine – these are those that don’t win very frequently, but when they do they usually pay out big.
