Dr Winmore Slot Review 2026
RealTime Gaming (RTG) | Released: February 2020 | Mad Scientist / Steampunk Theme
Dr Winmore is a video slot by RealTime Gaming (RTG) released in February 2020. Set inside the cluttered laboratory of a wild-haired, goggle-wearing mad scientist straight out of a steampunk fever dream, it takes a refreshingly different approach to slot design. Rather than the traditional reel and payline format, Dr Winmore uses a 5×5 grid with a Cluster Pays system, Cascading Reels, and a rising multiplier that builds with each successive win. The result is a game that rewards patience with a stream of modest, consistent payouts rather than infrequent large hits, making it a strong choice for casual players and anyone who prefers low-volatility gameplay.
The game quickly became popular at Springbok Casino, one of the leading South African RTG casinos, and its high RTP of 97.06% makes it one of the better-returning slots in the RTG catalogue. This review covers everything you need to know before playing.

Theme and Design
Dr Winmore leans fully into its mad scientist concept. The game’s protagonist sports the dishevelled white hair, oversized goggles, and slightly crazed expression that have become shorthand for cinematic scientific genius ever since Einstein. The visual treatment is warm and cartoon-like rather than dark and gothic, which keeps the tone playful and accessible throughout a session.
The 5×5 grid is packed with laboratory paraphernalia: test tubes, flasks, beakers, plasma balls, light bulbs, and battery cells fill the symbol positions in colourful abundance. Potions come in multiple colours including purple, green, red, blue, and orange, and each has a distinct visual identity that makes cluster formation easy to read at a glance. The four robot characters that serve as the game’s special symbols are particularly well-designed, each with a different look that hints at its function on the grid.
The animations that trigger on Cascading Wins are smooth and satisfying. When a cluster clears, the symbols dissolve in a flash of laboratory energy and new ones drop cleanly from above, keeping the visual pace quick without being overwhelming. For a 2020 RTG release, the production quality is genuinely strong.
Symbols
Dr Winmore uses two categories of symbols: standard pay symbols that form winning clusters, and special Robot symbols that interact with the grid in unique ways.
| Symbol | Type | Function |
|---|---|---|
| Dr Winmore | Wild | Substitutes for all standard pay symbols. Does not substitute for Robot special symbols. |
| Blue Robot | Special | Clears an entire row of symbols from the grid |
| Yellow Robot | Special | Clears an entire column of symbols from the grid |
| Green Robot | Special | Clears a block of surrounding symbols |
| Red Robot | Special | Clears a wider area of surrounding symbols |
| Plasma Ball | High-value pay | Highest-paying standard symbol |
| Battery / Light Bulb | Mid-value pay | Mid-paying energy source symbols |
| Potions (Purple, Green, Red, Blue, Orange) | Low-value pay | Lower-paying lab glassware symbols that fill the grid frequently |
The Robot symbols are the key to understanding the game’s rhythm. They appear randomly on the grid and remain in position once a winning cluster forms. When no winning cluster forms during a spin, the Robots still clear their designated area, which increases the Multiplier even on a losing cascade. This mechanic means that a series of non-winning Robot clears can set up a significant multiplier before a winning cluster eventually forms.
Bonus Features Explained
Dr Winmore does not pay on traditional left-to-right paylines in the conventional sense. Instead, wins are awarded when four or more matching symbols connect horizontally or vertically anywhere on the 5×5 grid. Diagonal connections do not count as a winning cluster, so only horizontal and vertical adjacency matters. The larger the cluster, the larger the prize. When the entire grid fills with the highest-paying symbol, the 3,000x maximum win becomes achievable.
Whenever a winning cluster forms, the symbols that make up that cluster are removed from the grid. New symbols then fall from above to fill the vacant positions, potentially forming new clusters without any additional bet. This process continues for as long as new winning clusters keep forming from a single paid spin. Multiple cascade sequences in a single spin are not unusual in Dr Winmore, and the Cascading Reels mechanic is the primary engine behind the game’s consistent small-win feel.
| Cascade Number | Multiplier Applied |
|---|---|
| First winning cascade | 2x |
| Second winning cascade | 3x |
| Third winning cascade | 4x |
| Fourth winning cascade | 5x |
| Fifth and all subsequent cascades | 6x (maximum, remains for rest of spin) |
When the Cascading Wins stop, the multiplier resets to 1x ready for the next paid spin. The Robot special symbols contribute to the multiplier even when they clear grid positions without forming a winning cluster, meaning the multiplier can build through non-winning Robot clears as well as through winning cascades.
RTP and Volatility
Dr Winmore carries a 97.06% RTP, which is well above the industry average of 95%–96% and places it among the higher-returning slots in the RTG catalogue. This means that over a very large number of spins the game returns approximately $97.06 for every $100 wagered. Individual session results will vary, but the high RTP gives players a better long-term return than most competing titles.
Volatility is classified as low. This is the defining characteristic of Dr Winmore as a playing experience. The Cluster Pays system combined with Cascading Reels means winning combinations form regularly, and the Robots clear grid positions on almost every spin. Players will rarely go many spins without seeing some activity on the grid. The trade-off for that consistency is that individual wins tend to be modest rather than spectacular. The 3,000x maximum win is theoretically achievable but represents an extreme outcome; realistic session wins are much smaller and spread more evenly across spins.
For players who find high-volatility slots frustrating or who are playing on a limited budget, Dr Winmore’s low-volatility profile is a genuine advantage. The game is designed to give back regularly, which makes it a comfortable session slot rather than an all-or-nothing proposition.
Bet Sizes
Dr Winmore has a modest bet range that reflects its casual, accessible positioning. Each spin costs 10 coins, with coin values adjustable between 0.01 and 0.25. This gives a total stake range of $0.10 to $2.50 per spin. The $2.50 maximum stake is low compared to most modern video slots, which means Dr Winmore is not suited to high-stakes players looking for large absolute payout amounts. At $2.50 per spin, the 3,000x max win equals $7,500 in maximum cash terms, which while attractive is well below the potential of higher-stake games from other studios.
For casual players, budget-conscious players, and those who want to extend their sessions without risking large sums, the low stake ceiling is a strength rather than a weakness.
Mobile Performance
Dr Winmore is fully compatible with mobile and tablet devices on both iOS and Android. The 5×5 grid layout is compact and translates well to portrait mode on smartphones, with the cluster formations and Robot clearing animations displaying clearly on smaller screens. Autoplay and turbo spin options are both available, making it a practical choice for mobile sessions where interacting with every spin becomes impractical.

The studio is known for producing accessible, player-friendly games with competitive RTPs rather than the feature-heavy, high-complexity releases associated with some newer studios.
Our Rating
Our Verdict
The Robot special symbols are the standout design element. Their grid-clearing functions add genuine unpredictability to each spin, and the interaction between Robot clears and the rising multiplier means that even spins without an immediate winning cluster can be building towards something significant.
The limitations are real. The $2.50 maximum stake is restrictive for players who want meaningful absolute payouts, and the low volatility means players chasing large single wins will find more satisfaction elsewhere. But for the audience Dr Winmore is designed for, it is one of the better RTG releases of the past several years. The 97.06% RTP alone makes it worth seeking out at any RTG-powered casino that carries it.
