If you’re looking to find a UK online casino with a playful sushi theme, Casushi might catch your eye. But beneath the colorful exterior, the numbers tell a different story. This isn’t a place where you’ll get rich quick – in fact, our tests suggest you’ll likely start in the red.

The Welcome Bonus: A Bitter First Bite

Casushi’s welcome offer is a match deposit with 50 bonus spins. Sounds decent on paper. But when we ran the numbers using a standard £100 deposit, the actual value after wagering requirements came out to -£32.74. That’s right – negative value. Out of 133 UK casinos tested, this ranked 89th. The bonus spins themselves? Their max RTP sits at a measly 91.25%, with a 40x wagering requirement. The spins alone were worth -£2.74 in our test. There’s no no-deposit bonus either, so you’re putting real money down from the jump.

Customer Support: Fast Emails, Limited Hours

Here’s where Casushi actually shines. Their email support responded in just 6 minutes during our test – that’s 10th fastest out of 133 casinos, and over 20 hours quicker than the UK average. Impressive. But there’s a catch: live chat is only available 9am to 10pm on weekdays and 11am to 10pm on weekends. No phone support at all. So if you hit a problem at 2am, you’re waiting until morning.

Game Library: Solid but Not Stellar

With 1,548 games, Casushi sits just above the UK average of 1,545. You’ll find slots, roulette, blackjack, live casino, poker, and bingo. No sports betting, no fantasy sports, no horse racing. It’s a decent spread, earning 4.2 stars and 66th place in our game selection test. The variety is there, but the depth isn’t remarkable.

Website Speed: Slow and Steady Loses the Race

Page load times averaged 2.90 seconds – below the UK average of 3.10, but still sluggish enough to rank 89th out of 133. If you’re impatient, this will grate. Every click feels like waiting for a slow elevator.

Overall Ranking: Middle of the Pack

When we combined all test scores – bonus, support, games, and speed – Casushi landed at 72nd out of 133 UK casinos. Its star rating averaged just under 2 out of 5. The bonus dragged it down hard; customer support was the only category that really impressed.

• Bonus & Promotions: 1/5 stars (52 points)
• Customer Support: 4/5 stars (33 points)
• Game Selection: 4.2/5 stars (66 points)
• Website Speed: 2.5/5 stars (89 points)

The Bottom Line

Casushi is a casino with a fun theme and fast email support, but its welcome bonus is a net negative, its game library is average, and its site speed is below par. If you’re after a quick, responsive support team and don’t mind a weak starting offer, it’s playable. But if you want real value from your first deposit, look elsewhere. And as always: gamble responsibly. If it stops being fun, call the National Gambling Helpline at 0808 8020 133.
