- Book of spells – Pick spooky items like cauldrons and crystals from a witch’s shelf to win free spins and multipliers.
- Lion’s pride – Select zebra carcasses for lion cubs to feed on, awarding coin prizes for each they eat.
- Dragon’s fortune – Choose treasure chests for the dragon to smash open with its fist or fiery breath.
The picking phase builds anticipation and immerses players in the theme before rewarding those lucky enough to uncover the best prizes. Matching the objects to the setting makes bro138 login bonus engagement feel native rather than tacked on.
Action sequences
Some bonus rounds play out as mini-action sequences, like.
- Raiders’ Run – Engage in a GET EVEN-style shooter as you raid tombs for treasures while dodging traps and enemies.
- Primal Hunt – Spear woolly mammoths in a skill-based challenge to stack up big prize multipliers.
- Sky Warriors – Pilot your jet through an aerial battlefield shooting down enemy planes and blimps.
Blending slot spins with action gaming elements like skill-based shooting or spear-throwing diversifies gameplay for more interaction using slot math mechanics under the hood.
Situational puzzles
Other slots build bonuses around situational puzzles and problems to solve, for example.
- Survivor – Complete mini-games like starting fires and building shelters to survive on a deserted island before a helicopter rescue.
- Westworld – Repair animatronic cowboy robots malfunctioning in the android-filled amusement park.
Tinkering with environmental puzzles or fixing glitchy robots integrates slot math mechanics into casual problem-solving gameplay.

Use bonus wins to hire helpful tribesmen who aid you on subsequent bonus rounds. Use magic earned in bonuses to upgrade strength, health, and spells for your wizard. Having persistent characters and gear that level up throughout gameplay adds engaging progression and customization.
