Lines Allstar 7s Hold and Win by Kalamba Games combines a Hold and Win mechanic with Cashpots, stacked Multiplier Wilds and Free Spins. In the base game, landing four or five special symbols awards the displayed value, while six or more trigger Hold and Win Spins, starting with three spins and resetting them when all reel positions are filled.
The slot includes four Cashpot levels that can be triggered when four or five Hold and Win symbols appear, including during the Hold and Win feature. Stacked Multiplier Wilds appear in both the base game and Free Spins with a 2x multiplier, while Free Spins are activated by three or more Free Spins symbols and use only high-paying symbols.
A buy bonus option lets players choose between Free Spins or Hold and Win Spins, and HyperBet offers three levels for adjusting play. The demo version is available to play for free, allowing players to practice before playing for real money and review the bonus features and symbol combinations.
