Crystal Sun

Play'n GO first attempted Crystal Sun under the working title Starblast, a name pulled from its release schedule after NetEnt raised the game's close resemblance to Starburst; it returned under its current name a few weeks later with the same mechanics behind a new set of symbols.

Bets run from 0.10 to 100 a spin across a 5-reel, 3-row grid that pays over 10 lines in both directions, set against a backdrop of nebulae, planets and starlight. Five coloured planets make up most of the paytable, alongside lucky-seven and diamond symbols, with the diamond paying the most at 16x the stake for five in an active line, and the paying-both-ways structure means a line of matching planets counts whether it reads left to right or right to left.

A star wild appears only on the three middle reels and carries a x1, x2 or x3 multiplier. Landing one expands it to cover the whole reel and triggers a respin with that wild locked in place; if a second or third wild lands on a later respin it locks in too, and with all three reels covered the combined multipliers can reach x9. Because only three of the five reels can ever hold a wild, the respin sequence is capped at three rounds even when every one of them lands.

The wild-and-respin loop is the engine behind the whole game, repeating for as long as fresh wilds keep landing on those three reels. That keeps individual rounds quick, with the win potential concentrated almost entirely in how many of the three locking positions fill up before the sequence runs dry.

Play'n GO offers five RTP settings for different markets — 96.60%, 94.50%, 91.57%, 87.42% and 84.57% — with 96.6% shipped as the default, rates the game 10 out of 10 for volatility, and caps wins at 4,000x the stake.
