The short version
A Megaways pokie looks like an ordinary slot until you notice the reels are different heights, and that they change every spin. Megaways is not a game but a reel engine, licensed from the Australian studio Big Time Gaming to dozens of other studios. Its one idea is simple: instead of a fixed grid, each reel shows a random number of symbols on each spin, so the number of ways to win is never the same twice. Everything else about how a pokie works, covered in our how online pokies work guide, still applies: a random number generator draws the result, and the game pays back a set share over its life.
How the ways are counted
The usual Megaways layout is six reels, each showing between two and seven symbols on a given spin. A win is any run of matching symbols on adjacent reels starting from the left, regardless of which row they land in. To count the ways, you multiply the number of symbols on each reel together. With seven symbols on all six reels that is 7 × 7 × 7 × 7 × 7 × 7, which is 117,649, the famous figure on the box. On a spin where the reels come in short, the same game might offer only a few hundred ways. That recalculation every spin is the whole mechanic.
Cascading wins
Most Megaways titles pair the changing reels with cascades, also called tumbles. When a win lands, the winning symbols are removed and new ones fall into the gaps, which can form another win from the same spin, and another, until nothing new connects. Cascades are often where a free-spins round does its damage, because a single triggering spin can chain into a long sequence. The maths is still fixed: cascades are part of how the game reaches its return, not a bonus on top of it.
Volatility and RTP
Megaways pokies lean high volatility. The combination of shifting ways and cascades is built to produce long flat runs broken by rare, large wins, which is exactly what high variance means. That has two consequences worth planning for: a small balance can disappear faster than on a low-volatility game, and clearing bonus turnover on a high-variance Megaways title is risky, because the balance can empty before the wagering requirement is met.
RTP is a separate question. There is no single “Megaways RTP”: each title is built around a figure the studio sets, and, as with any online pokie, the operator can choose a lower-RTP version. The number in the game’s info screen is the one that applies at that site; our RTP guide shows where to read it.
Free spins and the big wins
The free-spins round is where a Megaways pokie earns its reputation. Many add an unlimited win multiplier that climbs with each cascade and does not reset for the rest of the feature, so a good run of tumbles during free spins is how the advertised maximum wins are reached. Those maximums are real but rare; they are priced into the same long-run return as everything else, not a sign the game is paying more than its RTP.
Spotting a genuine Megaways pokie
Only titles licensed by Big Time Gaming may carry the Megaways name, and the studio that built a game is named in its info screen. Plenty of studios run their own changing-ways engines under other names; those are legitimate games, just not Megaways. The warning signs are the same as anywhere: a famous-looking name with no studio behind it, or a game that shows no RTP at all, which our guide on whether pokies are rigged covers, and which the Lightning Link guide shows in the context of copied games.
