Goals from Scott Arfield, Kemar Roofe and two from Joe Aribo put them ahead at the interval and Roofe again struck in the second half followed by Brandon Barker and James Tavernier twice.
It’s the first time since 1981 Rangers have hit eight goals at home.
It was hard to keep up at times, but here’s each of today’s goals, in order, below.
