Wild Worlds

Wild Worlds by NetEnt is a 5-reel, 5-row video slot with an Avalanche mechanic and wins formed by three or more matching symbols on horizontal or vertical lines. The game uses a futuristic city setting, with bird heroes facing monsters across a cartoon-style grid. In the demo version, players can play for free and examine the main rules before playing for real money.

The slot includes Hero Wilds, which can appear after a winning combination clears matching Hero symbols, and a random Destroy Feature that leaves only one symbol colour on the reels when no win is made. This can create a fresh Avalanche round and more chances for line-up combinations. Symbols cover high, medium and low-value icons, with Scatter symbols shown as a wheel.

Three Scatter symbols trigger 8 Free Spins. During this bonus round, the game moves through three worlds: Dark Forest, Ice World and Fire Lands. Each world features Captains and a Boss with health points, while individual Hero Attacks are charged by matching hero symbols and can deal damage during the bonus sequence.
