Neon Staxx

Neon Staxx is a video slot from Netent with five reels and four rows, as well as forty fixed paylines. The game's theme is retro 1980s with neon colors, synth music, and animal symbols such as lions, panthers, and eagles against a futuristic background. One of the main features is "SuperStaxx," where a symbol number is randomly chosen and stacked on the game board on one or more reels – this applies to both the base game and during free spins. Scatter symbols trigger free spins when three or more land anywhere on the reels; three give ten free spins, four give fifteen, and five give twenty. During the free spins, the SuperStaxx mechanic changes so that only high-value Predator symbols or Wild can be chosen as stacked symbols. The Wild symbol acts as a substitute for all other symbols except Scatter in winning lines and can also be the symbol that is stacked during the SuperStaxx feature. The game does not have a bonus buy feature. Minimum and maximum bets consist of multiple levels and coin values so that players with both small and larger budgets can participate.

You can play it for real money.
