In-depth review: Zero Orbit review: a cluster slot that keeps score by row
What kind of slot is Zero Orbit?
Zero Orbit is a cluster slot from Nocturn Play on a grid of 6 reels and 5 rows. There are no paylines: a win needs a group of at least 5 matching symbols linked horizontally or vertically. Winning symbols vanish, new ones drop in from the top, and the cascade continues as long as new clusters form. The game's signature is the column of planets beside the grid, one for each row, which act as multipliers from ×1 to ×10. The top win is 5,000× the bet.
Planets that level up
At the start of every paid spin, all five planets show ×1. When a cluster wins, it is multiplied by the highest planet among the rows it covers. Then each of those planets climbs one step. So a cascade that keeps finding clusters on the same rows gets stronger with every drop: ×1, then ×2, then ×3, and so on up to ×10. A wide cluster that spans several rows picks the best planet of the lot and pushes all of them up at once.
Comets and portals
The comet is the wild. It stands in for any symbol except the portal to help complete a cluster, and it has a bonus of its own: the moment a comet lands, the planet on its row climbs one step, even before any win is counted.
The portal is the scatter. Land 4 or more anywhere and the portal opens on free spins: 10 spins for 4 portals, 12 for 5 and 15 for 6 or more, with a cash prize for the portals themselves. Inside the bonus the planets no longer reset between spins. Whatever level they reach stays for the rest of the feature, so the second half of a good bonus can play with ×6 or ×8 planets on several rows. Three portals during free spins add 5 more spins, four or more add 8, up to 40 spins in total.
Symbols and bonus buy
The lower symbols are four cut gems in cyan, violet, amber and pink. Above them come the crystal, the rocket and, at the top of the paytable, the ringed planet. Bigger clusters pay much more than the minimum five: the table climbs steeply all the way to clusters of 25 or more. If you do not want to wait for the portals, pressing Bonus takes you straight into 10 free spins for 35× the bet, planets keeping their level throughout.
The mascot
A small three-eyed alien in a golden spacesuit sits on an asteroid at the left of the grid, juggling tiny planets. It cheers the big wins and pulls a face at the near misses, such as a spin that stops one portal short of the bonus.
Next to other cluster slots
Play'n GO's Reactoonz made cluster pays and cascades a staple, with its charge meter and giant Gargantoon. Zero Orbit uses a smaller 6×5 grid and puts its whole twist into the row multipliers, which you can follow at a glance in the planet column. For a slot with a completely different pace, look at Viking Raid or the noir lines of Black Vigil.
Zero Orbit is free to play on nocturnplay.com in portrait or landscape, with autoplay and turbo for faster sessions. See the other slots in the Nocturn Play catalogue.
