Le Zeus by Hacksaw Gaming

Le Zeus is Hacksaw Gaming’s newest slot to feature Smokey Le Bandit, the master of disguise! Smokey is back, and he’s taking a lightning bolt to mystery symbols and a variety of bonuses.

It’s always interesting to see new Hacksaw Gaming slots featuring Smokey Le Bandit. The thieving furry critter’s slots outings get more elaborate with each release. This time out, Smokey is assuming the ultimate disguise as he grabs his lightning bolt and Zeus outfit.

Le Zeus is, like previous Le Bandit games, a 6-reel slot with cascading reels in play. Mystery symbols may land on adjacent reels to reveal wilds or high-paying symbols.

You may even uncover a mystery reel with random multipliers. The multipliers featured on coins and diamonds are worth up to 500x.

You trigger the Bolt & Run bonus by landing three scatters anywhere. Mystery symbols become sticky every time they appear. Plus, coins may land with a minimum multiplier of 1x.

Alternatively, you activate a Mystery Meter by triggering free spins with four scatters. Fill the Mystery Meter with 25 symbols to earn a re-spin. The screen only displays coins, diamonds, clover symbols, or pots of gold.

Finally, you trigger the Hidden Epic bonus by triggering the bonus with five scatters. Again, you win eight free spins with the Bolt & Win mechanic. However, reels 2–5 are filled with Mystery symbols from the beginning of the feature.

There’s a lot of high-variance action in Le Zeus. However, like all of Hacksaw Gaming’s Smokey Le Bandit slots, there are opportunities to trigger a mighty jackpot. Give the game a spin for free today at Vegas Slots Online.      

Cowboy Showdown by Iron Dog Studio

We head to the Wild West for the next of our best new online slots of the week. Pull the trigger to unload your six-shot and pick up Prize Coins.  

The battle bonus gets another outing in Iron Dog Studio’s latest online slot: Cowboy Showdown. It’s a 5-reel slot where two cowboys wait to duel it out for coins.

You trigger the Cowboy Showdown by playing six spins. Win or lose, the Cowboy Showdown activates, and the Hero and Villain battle it out.

One cowboy emerges victorious at the end of the shootout. The Hero triggers cash values that are collected on the reels. However, a Villain victory releases coins onto the Wanted Bounty.

You unlock the Wanted Bounty during the free spins bonus, triggered with 3–5 scatters. Don’t forget, the Wanted Bounty may also have special prize coins added worth up to 1000x.

The showdown bonus is a tried-and-tested feature of some of the best online slots. The 10000x total cumulative payout in Cowboy Showdown adds to the appeal, as does the Wild West vibe. Give the slot a spin for free and see what you think.   

Crystal Cave 1000 by Nemesis Games Studio

Win up to 25,000x stake in Crystal Cave 1000, the newest fantasy-themed slot from Nemesis Game Studio. Trigger same-cell explosions to build progressive multipliers worth up to 1024x.  

Italian developer Nemesis Games continues its good run of online slots in 2025 with Crystal Cave 1000. It offers an attractive design (even with an option to select your preferred background) and super-slick gameplay. Plus, you can accumulate multipliers to build your bankroll during the base game.

Crystal Cave 1000 uses a cascading reels mechanic on each spin. Winning clusters are removed and replaced by new symbols dropping down. Plus, exploding symbols leave behind a highlighted position on the reels.

A multiplier is displayed (starting at 2x) that increases with every explosion that occurs on that position. You can potentially secure a multiplier of 218x for each position containing an exploding symbol.

Crystal Cave 1000 also features one of the best free spins bonuses we’ve seen in recent cascading reels slots. You win up to 30 free games by landing up to seven scatters anywhere. Plus, highlighted multipliers become persistent and remain in place for the duration of the bonus.

I love the customizable play area in Crystal Cave 1000. Also, the slot plays beautifully if you’re online or on your smartphone.

Looking for a generous new slot to add to your collection? Look no further than Crystal Cave 1000, which you can spin for free at Vegas Slots Online.  

Squeak by Gamevy

Trigger up to seven features in Squeak, the cartoon-themed slot with a difference from Gamevy. Play up to 100 paylines in the Stacks free spins, or activate one of the four giant fixed jackpots.   

Squeak combines the best imagery from Hacksaw games like Rip City with the horror vibes of NoLimit City slots. The 5-reel slot plays out like Walt Disney from Hell, with a demonic Mickey Mouse-a-like presiding over the game area.

Wilds substitute for all symbols except scatters in the game. Plus, wild symbols nudge down to fill an entire reel during the Stacks bonus.

Squeak’s biggest selling point is its bonus feature variety. You win five free spins in the Stacks bonus, with 100 paylines in operation. This is the bonus where nudging wild reels come into force.

Alternatively, activate the Bounty bonus feature with ten free spins and the chance to win one of the fixed jackpots. Collect unique letters spelling out a jackpot type (e.g., GRAND) to win the corresponding prize.

Play it lucky and you’ll trigger the Stacks Bounty super feature. You win ten free spins across 100 paylines, while the reels grow to six rows. You also have a chance to take down one of the big fixed jackpots.

Squeak is one of the best new online slots of the week for its breadth of bonus action and jackpot levels. Give it a play for free and see what you think.
