Nothing to learn, frequent small wins and a calm pace.
No free spins and a low ceiling.
Slots are capped at £5 a spin in Britain.
Short answer: Starburst is the gem slot: jewels on ten lines paying both ways, with an expanding wild that re-spins. It is low volatility with a 500x maximum.
Why it is a first slot
Nothing to learn, frequent small wins and a calm pace.
Starburst's one feature is worth describing exactly. A wild appears only on the middle three reels, expands to cover its reel and triggers a re-spin with the wild held. Another wild on that re-spin does the same, up to three in a row. All ten lines pay from either end, which is why wins feel frequent.
