Book of Dead vs. Age of Gods: Comparing the Main Features

During our 10 hours of testing what each slot delivers at over 20 online casinos in Ireland, analyzing the effect of the Wild & Scatter symbols, and checking the betting limits with real money, we discovered the 10 best features that would make you choose either slot.

Book of Dead has a significant advantage over the other slot, with an RTP of 96.21%. Stakes are also more flexible with Book of Dead casino bonuses, where you can bet from €0.01 to €50. However, our senior writer Cosmin Brehoi noticed during his research that the unique features put the Age of Gods slot to an advantage, given that it has 4 different Progressive Jackpots, while the other slot only has one.

CasinoAlpha’s Recommendation: Try Book of Dead Free Spins

After testing both slots with 15 different free spins bonuses, our CasinoAlpha experts recommend playing with Book of Dead free spins, as this is the best online slot to play free spins at Irish online slots sites with real money. The main reason is that the Book of Dead slot RTP is the highest of the two slots – 96.21% – while the Age of the Gods slot RTP is only 92.08%.

Book of Dead’s expanding symbols & free spins feature also convinced us of its high win chances. Our expert senior writer Cosmin Brehoi argues that the slot’s high volatility and Risk (Double) Game feature, though risky, works best with Book of Dead free spins no deposit because more rounds mean more chances of high payouts. The Double Game is a popular feat of games at new slot sites with online casino slots in Ireland because it can double your profits and offer an extra game.

Age of Gods: What You Need to Know

The Age of Gods slot has been a favourite of Irish players since 2016. You’ll discover 4 different jackpots, all progressive, and 4 different bonus spins games that trigger on all 5 reels and 20 paylines when you get a winning combination of symbols.

When you play Age of the Gods at the newest online casinos, the maximum bet per line is 200 credits, worth a €40 stake, which is relatively low. However, the graphics are iconic, as they’ve been created by Playtech, and they take their inspiration from Greek mythology.

What Features Make A Good Slot?

Let’s discover what are the key elements that make a slot game suitable according to our experience:

1. A high RTP of over 97% is the mark of a slot that has long-term winning potential.
2. Slots with progressive jackpots are well worth the maximum bet, as there’s a good chance of getting a big win.
3. A slot game’s payline number is also necessary to determine the number of chances you have to get winning combinations on a reel spin.
4. You should also look for bonus rounds or similar bonus features that help you adjust your gameplay as you go.
5. You’re also supposed to be on the lookout for the gamble feature, as this could double your reward or make you lose your whole hand.
6. Be aware of the volatility—a safe slot has low volatility, while a high-volatility reel makes your stakes much riskier and your potential prize larger.
7. A good slot should also be well-branded. That means it should be developed by Play’n Go, Microgaming, NetEnt, and other well-known developers.
8. Look for a slot that’s eligible for a hefty casino bonus or ongoing promotion that will increase your play budget.
9. Slots that win a spot on the CasinoAlpha website also have big maximum cash payouts of at least 10000x bets.
10. We noticed players are taken aback by slots with modern graphics & colour schemes optimized for mobile playing that load fast, which are all classic feats of a top slot. Optimized Graphics – Modern 3D graphics and immersive animations bring games to life.

Best Free Spins Casino Bonuses to Use – Our Top Picks

All free spins bonus our experts selected for this table are part of Ireland’s latest best free spins promotions and have been tested with real money and live accounts to give you the best chance to win whether you’re choosing to play either of the two slots.

The selection is varied, so you can find low-wagering rewards or promotions with regular to higher playthroughs if you like a bit of a challenge. We did not forget about new IE players who may not be familiar with wagering yet, so we included a few no-wagering bonuses as well.

While we recommend getting offers with 50 free spins that give you more chances to win, you should browse through a more varied collection of casino bonuses to decide with all options in sight.

Which is the Best Slot for Mobile Gameplay?

While Book of Dead has a simple structure of 5 reels & 10 paylines that loads fast on the best mobile casino sites in Ireland, Age of Gods has more complex graphics that are slower on smartphones. For instance, when we researched Slotbox Casino, we noticed that the Book of Dead slot loaded faster on the casino mobile platform and rolled without glitches throughout the session.

The Age of Gods slot recovers this deficit in Irish casino apps. Once it’s downloaded, the graphics don’t make much of a difference, as we saw at Novibet Casino, where we reviewed both its Android and iOS apps. But the other slot didn’t have this deficit from the start, which is why we recommend it for mobile players as the better mobile slot.
