Beach Invaders is a 5-reel, 4-row online slot from NetEnt with 30 paylines and a 96.09% RTP. The game uses a high-volatility structure and a minimum bet of €0.10, with play available up to €40.00. The theme places a sunny beach setting alongside alien-style symbols and a progress-based feature system.
The main mechanic is the Locked Wild Progress Bar. Pink plasma ice cube patches can attach to paying symbols and build the bar across four milestones. Reaching these stages triggers Expanding Wilds that cover a full reel and can lock in place for up to four spins, with each new wild taking over the reel and continuing the progression.
A bonus round starts with 3 Free Spins scatters, awarding 10 free spins. In this demo version, players can play for free and practice before playing for real money while seeing how the Free Spins feature works: wilds expand, then move one reel to the left on each spin, shrinking by one symbol height as their multiplier increases from 1x to 5x.
