There's no definitive answer to this question since slots video poker games are purely luck-based and there's no guaranteed way to win. However, playing online slots at certain times may increase your chances of winning or hitting a jackpot. Many online casinos offer progressive jackpot slots, which means the jackpot amount keeps growing each time someone plays the game. Jackpots typically hit around midday or early afternoon, so playing slots online at these times could improve your odds of winning. Additionally, avoid playing slots during holiday weekends when more people are likely to be gambling. With more players comes increased competition for the jackpots, so you'll want to aim for quieter days and times if possible.
