What it costs to play

Megaways is a reel mechanic rather than a game. On the standard six-reel version each reel shows between two and seven symbols, and the number of ways to win is recalculated from that layout on every spin. Seven symbols on all six reels gives the number the marketing uses: 117,649.

We earn a commission when a reader opens an account through the links above; it never changes the order, which follows our own checks. 18+ only. Play within your limits — support at BeGambleAware.org and GamCare 0808 8020 133, and you can self-exclude from every UK licensee through GAMSTOP.

How the maths actually works

Wins are formed left to right on consecutive reels, and the symbol’s position on the reel does not matter — only that it appears. Multiply the symbol counts of the six reels together and you have that spin’s ways. Two symbols on every reel gives the floor: 64 ways.

So the spread between the worst and best layout is enormous, and most spins land nowhere near the top. The headline is a geometric maximum, not a measure of generosity, and a slot with 117,649 ways can return less than a 20-line game.

The features that usually come with it

Two companions are almost standard. Cascades remove winning symbols and drop new ones into the gaps, so one paid spin can resolve several times over. Free spins rounds typically add a multiplier that rises as cascades continue, and that round — not the base game — is where the large results come from.

It is worth reading the paytable before assuming otherwise: on many Megaways titles the base game is deliberately thin, and volatility is high enough that a long stretch of nothing is ordinary rather than unusual.

What it costs to play

The British stake cap applies here like anywhere else: £5 per game cycle for customers aged 25 and over, £2 for those aged 18 to 24. The limit is tied to the game cycle, not to the number of ways on screen, so a spin that opens 117,649 ways costs no more than the stake you set.

Cascades belong to the cycle that paid for them, which is the practical reason the cap is written that way — see our note on stake limits. For the rest of the reel formats, the games section covers them one by one.
