Why Megaways is on a hundred games and xWays is on one studio's games only

Slot Mechanics

Two slots can use almost the same idea and one appears under fifty studio names while the other never leaves its maker's catalogue. The difference is not quality or maths. It is whether the studio decided to license the mechanic out.

Megaways came from Big Time Gaming, introduced in 2016 on Dragon Born and made famous later that year by Bonanza. The mechanic replaces fixed paylines with reels whose symbol count changes every spin — six reels, each showing between two and seven symbols — so the number of ways to win changes as the reels land. The headline figure, 117,649, is what you get when all six reels show seven symbols: seven to the sixth power. Wins are paid for consecutive matching symbols from the leftmost reel, and winning symbols are removed so new ones can drop in.

The part that explains the lobby is commercial. Big Time Gaming chose to license the technology, and in 2018 Blueprint Gaming acquired rights in it — which is why studios with no connection to BTG ship Megaways titles, and why the trademark appears with a ™ next to it everywhere.

The house-mechanic model

Other studios took the opposite decision and kept their named mechanics inside their own catalogue:

None of these is a worse idea than Megaways. They are simply not for sale as a format, so you will not find an xWays game from another studio — and if you see the word used loosely by an affiliate page, it is describing a lookalike, not the mechanic.

Why this matters when you are choosing a game

Three practical consequences, in order of usefulness:

How to read a mechanic name on a game tile

A name on the tile answers exactly one question: which framework produced the reel behaviour. It does not tell you the return-to-player of the build you have been served, the maximum win, or whether features were removed for your market. Those three live in the in-game information screen, and they change between builds — see one slot, several RTP builds and where bonus buy is not available.

One more thing worth knowing about licensed formats: the licence fee is a cost in the game's economics. It does not come out of the RTP by any rule — the certified figure is the certified figure — but it does shape which studios bother with the format and at what price point they aim the game.
