We understand that losing can be frustrating. Keep in mind that all slot games have a certain Return to Player (RTP) percentage which determines how much of a bet will be paid back over time, however it is calculated for all players playing in that particular period. All slot machines operate on the basis of randomly generated numbers, and neither losses nor wins are personal, it's all about mathematics.
If you feel like you are losing more than you can afford, or gaming is negatively impacting you, consider taking a break or using additional options of self-restraint.
