A non-sticky bonus, also known as a parachute bonus, is highly popular because it prioritizes the player's real money balance first.
In this setup, you play with your deposited funds before touching the bonus credit granted by the casino.
The main advantage is that you can withdraw your winnings and your initial deposit at any time, as long as you have not started using the bonus funds.
Once you enter the bonus balance, the wagering requirements typically kick in and the funds become "stuck" until those conditions are met.
This mechanic offers a safety net for players, giving them a second chance if they lose their initial deposit while maintaining the freedom to cash out early.
Because of its player-friendly nature, many experienced gamblers specifically seek out non-sticky offers over traditional bundled bonuses.
