Make a deposit of at least $10, and you’ll unlock the second part of the welcome offer – a 100% deposit match up to $1,000.

The $25 Casino Bonus is enough to get you 100+ spins on popular slots like 88 Fortunes Jackpot Festival, Cats, and Thunderstruck Gold Blitz Extreme.

Among the 3,000+ BetMGM Casino games, we’re huge fans of the exclusive titles you won’t find anywhere else.

Such picks include Roaring Cash Link & Win, The Wizard of Oz Over the Rainbow, and MGM Grand Millions.

Caesar’s Palace Casino – Get A $10 Deposit Match Plus $1,000 Deposit Match

This brand ranks high on any list and any month because it’s a top spot in every sense.

Join the site this March, and you can grab the Caesar’s Palace welcome offer of $10 FOR FREE.

Complete your first deposit of at least $10 to get a 100% up to $1,000 match plus 2,500 Reward Credits when they wager $25.

Of course, Caesars Rewards are there to reward your loyalty to the brand with extra benefits throughout the month.

Another of its main pros is the rich game selection of slots, progressive jackpots, live dealer games, and even some exclusive titles (Caesars Cleopatra, Caesars Fortune, etc.).

Most of these slots have minimum bets of $0.20, so you can spin their reels hundreds of times with the welcome bonus funds.

Hard Rock Bet – Get 500 Free Spins Plus $1,000 Deposit Match

Hard Rock Bet’s welcome offer stands out as a generous one this March.

As a new player at Hard Rock Bet, you can get a 100% deposit match of up to $1,000 and 500 free spins when you deposit $20.

The deal has fair rules and gives you hundreds of spins on top slots, such as 88 Fortunes, Cleopatra, and Bonanza!

If you play at Hard Rock Bet throughout March 2025, you will automatically start earning Reward Points and Tier Credits.

These help you improve your player status and grab extra perks like Mystery Wheel spins, Bonus Bets, and so much more.

PlayStar Casino – Grab 500 Free Spins Plus $500 Deposit Match

There isn’t a PlayStar Casino no-deposit bonus for new players, but it does offer a sweet welcome package on your first three deposits.

On your first deposit, you can get 100% up to $500 and 100 free spins.

On your second and third deposits of at least $20, you become eligible for two other batches of 200 free spins each.

If you get the whole deal, you end up with a total of 500 free spins for five selected slots: Double Stacks, Bee Hive Bonanza, Twin Spin Megaways, Super Stars, and Divine Fortune Megaways.

Throughout March 2025, you can also try your luck on the $1,000 BlackjackPot or the Concierge Cashdrop Jackpot.
