Played on a 5×3 format with 10 fixed Paylines, NetEnt’s 2012 release Starburst is an absolutely classic game, and arguably the most popular online slot ever.
It uses a win-both-ways mechanism, is low-to-medium variance, and RTP is 96.09%.
Set in outer space, its symbols incorporate five jewels, a lucky red 7 and bars. The Wild appears only on reels 2 through 4. These icons increase in size to give fully Wild reels with respins which can ultimately result in a hat-trick of Wild reels.
Respins run with the original Wild reel locked in place, and the process continues until there are no further Wilds in any respins. This feature kicks in when a Wild displays on any of its reels.
Starburst is a comparatively simple game, often copied but never beaten, and endlessly mesmerising, despite the lack of perks like free spins; in Starburst, that never seems to matter.
