Invading Vegas: Las Christmas

Play'n GO dresses its 2022 alien-invasion release in tinsel for Invading Vegas Las Christmas, recasting the wrecked Sin City skyline in a coat of snow and festive lighting. The base game still shows a snapped Eiffel Tower replica and a downed UFO scattered across the strip, while triggering the bonus round swings the scene to a rebuilt, fully lit city, as though the fight had already been won. The tone leans toward comic chaos rather than genuine menace, right down to a snowman modelled on a certain quiffed crooner sitting among the top-paying symbols.

Spins play out across a 5x3 grid with 20 fixed paylines, evaluated left to right, and bets run from 0.10 to 50 per round. Card-suit chips fill the lower end of the paytable, while five character symbols carry the higher values, topped by the snowman; five matching premiums pay between 1.6x and 8x the bet, with the chip symbols worth up to 0.8x. Wild symbols substitute for every regular pay symbol and complete a full line for 30x on their own.

A Mystery Symbol feature underpins several of the mechanics: any mystery symbol that lands can turn into a matching pay symbol, or into a wild carrying a multiplier of x2, x3, x5 or x10, and where several multiplier wilds combine on one line their values are added rather than multiplied. That mystery mechanic feeds into Lock on Re-spin, which fires when the first two reels show a complete stack of one matching symbol, wilds included, without producing a win — the outer reels then lock while the centre reel spins again, and this re-spin can itself open the free spins round.

Stacked wilds landing on the middle reel during that re-spin become a Walking Wild, travelling one reel to the right with each further re-spin until it reaches the last position, at which point every reel gets one final re-spin. As it travels, the Walking Wild seeds between three and twelve extra mystery symbols across the grid, though scatters are locked out for as long as it is active — unless three land on the triggering near-miss spin itself, in which case the walking wild is skipped and free spins begin immediately.

Collecting three scatters anywhere awards twelve free spins, and landing three more during the round adds a further twelve, up to a maximum of 120. Direction flips inside the bonus: the Walking Wild now heads left instead of right, and the reels that can carry stacked high-value symbols shift toward the left rather than the right.

Play'n GO ships Invading Vegas Las Christmas with a medium-volatility profile, a default RTP of 96.2% and four lower configurations down to 84.2%, and caps the top prize at 2,500x the bet. Between the mystery reveals, the re-spin chase and the walking wild's expanding mystery drops, the bonus rounds carry most of the swings, while the base game ticks along on wild lines and the odd mystery hit.
