Now that I've told you about the summary, intro, graphics, music, and sound effects, up next will be the key game features.
At OLBG we write slot game reviews that include up-to-date info about essential features such as the theme, paylines, reels, bet range, and bonuses. I’ll finish off the review by talking about my play experience, first impressions and my expert verdict.
Theme - World War 2
WWII took place from 1939-1945 and affected everyone around the globe, the effects of which are still being felt today in global politics so it's a theme which means a lot to most folks. During the game, you'll spy on plenty of familiar items such as trenches, soldiers and 1940s military uniforms. The background image during the base game focuses on the military technology side of war, where you'll see large maps and model planes helping to decide where to attack from. The bonus games are about the battles so expect plenty of gunfire, explosions and action.
On the reels, you'll discover various military items, which, in order of highest value, first start with Stukas, which were German military aircraft; secondly, there are German tanks called Panzas. Next up are Howitzers, which are still used by the military today and are long-range cannon-type weapons. There are game features named after these weapons, too, so check out the Play Experience & First Impressions section for more info about these. The lower value symbols are depicted by a Fighter Pilot, an Anti-Air soldier, Foot-Soldier and a Commando.
Reels
The D-Day slot game is made up of 5 reels and 3-4-5-4-3 rows to play with.
Paylines
There are 10 paylines available where you can trigger wins on the D-Day slot game.
RTP
You'll have seen Return to Player or RTP as it's most commonly referred to on slot sites. This is a way of measuring theoretically what percentage of players' stakes will be returned to them over the long term. So the higher the number the better for players, the D-Day rate is slightly over the average at 96.12%.
Nolimit City uses this RTP figure as a default value, so if you shop around, you’ll find different rates. To save you some time, we’ve identified a few at some of the popular UK online casinos and added them to our table below.
It's worth noting that RTP is just one consideration when deciding which site to play at. You should also think about payment options, game library, customer support and welcome bonuses and deals. Our casino reviews look at this info and much, much more.

Stake Range
There’s a wide bet range for the D-Day slot game which starts at £0.20 and goes right up to £100.
Max Win
The max win for the D-Day game is a mega 55,555 x your stake and this feature is named 'Mission Accomplished.'
Wild Shape
There is an Atomic Wild symbol for the D-Day game. Here a random position is selected on the reel area and is then transformed into a Wild symbol with a random multiplier of 10, 20, 30, 50 or 100. If the chosen position is already Wild, then +1 will be added to the randomly chosen multiplier. If multiple features trigger at the same time, then Atomic Wild will always trigger first.
Free Spins
There are 3 free spins round to enjoy for the D-Day slot game. First up are the Neptune Spins, which include 2 features. You enter the round by landing 3 Scatter symbols. Once the round is triggered, you will get a pick-and-reveal option, which will reveal 2 out of 5 features which are weapons. If a Scatter lands on reel 5 while triggering Neptune Spins, then the Atomic Wild feature will get activated, and you will get only 1 option to pick and reveal from the remaining 4 features. Each revealed feature will activate at least once during Neptune Spins.
Secondly, there are Invasion Spins, which include 3 features. Landing 4 Scatters activates this round. Once triggered, you will get a pick-and-reveal option, which will reveal 3 out of 5 features. If a Scatter lands on reel 5 while triggering Invasion Spins, then the Atomic Wild feature will get activated, and you will get only 2 options to pick and reveal from the remaining 4 features. Each revealed feature will activate at least once during Invasion Spins. And finally, there are the action-packed Overlord Spins, which include 4 features. Landing 5 Scatter symbols will activate the Overlord Spins. The Atomic Wild feature is guaranteed, so you will get a pick-and-reveal option to reveal 3 features out of the remaining 4 features. Each revealed feature will activate at least once during Overlord Spins.
Play Experience & First Impressions
Wow, from the second I strapped in and started playing, I was a fan. The strong storyline, top features and immersive experience ticked a lot of boxes. The bonus rounds were heart-pounding with plenty of layers but were, importantly, easy to follow. The pick-and-reveal 'Choose Your Weapon' feature was a top idea, and this played out superbly on the screen as the weapons fired across when playing. The Bonus games included an extra layer fitting across the screens, and this feature appears on most NLC games and really makes an impact.
There were some other outstanding features, including the Howitzer feature. Here, it randomly chooses any 1-7 paying symbols and turns them into Wild symbols apart from the Commando symbol or Wild symbols. There is also the Panzer feature, where 2-5 Panzers can randomly appear in different rows, with 1 Panzer allowed per row. Every low-paying symbol on these chosen rows gets transformed into a Wild symbol except the Foot Soldier symbol. If Wild is present on the chosen row, the multiplier increases by +1 for that Wild symbol, which can make a huge difference to gameplay.
The Stuka fearure appears diagonally either from left to right or from right to left. It splits all paying symbols and doubles their size, which can bring in wins. There is a maximum of 7 Stukas per spin and one Stuka per diagonal. Finally, there is the Bomber feature, where 2-5 Bombers can randomly appear on different reels, and there is 1 Bomber per reel. All the paying symbols on these reels will be transformed into Wild symbols from top to bottom. If the Anti-Air symbol is present on the chosen reel, Wild transformation stops just above that Anti-Air symbol. If Wild is present on the chosen reel, then the multiplier increases by +1 for that Wild symbol. So there are buckets of fears to enjoy when playing D-Day.
