How to play Starburst

  1. Choose a stake; ten lines pay both ways.
  2. Spin. Matching gems on a line from either edge win.
  3. A wild on reels two, three or four expands to fill the reel.
  4. The reels re-spin with the wild held; another wild repeats it.

The mechanic

There is one feature. A Starburst wild stretches over its whole reel, locks, and triggers a re-spin. If a second or third wild appears they do the same, so the best outcome is three wild reels across the middle. More on expanding wilds.

The maths

Starburst returns 96.09% of stakes over the very long run by default, which is a house edge of 3.91%. Its low volatility describes how unevenly that return arrives.

Theme and look

Jewels on a starfield with an arcade soundtrack. It was released in 2012 and still looks clean.

A typical session

A typical session ticks along. Small wins arrive every few spins, an expanding wild appears now and then, and a second or third wild turns a re-spin into the best moment of the night. The balance drifts down gently, with few shocks in either direction.
