GO Mammoth Reviews 

Great easy experience and enjoying the league

The league is great fun and the gomammoth staff, from the umpires to the table are making everything runs swiftly. I can't recommend them enough

I've had an overall great experience with the go mammoth netball leagues. They are well co-ordinated with great umpires and like-minded, netballers. There are sometimes a few issues with logistics, but a minor issue. Overall would recommend. School 21 netball on Saturdays.

Well organised, great umpires, I really do have fun playing even though my team never wins, the other teams are very gracious. My only con is the lighting on the court, it needs replacing especially going in to autumn.

The netball league with GoMammoth is great. Their website info could be better - I'd have signed up earlier if I'd realised I wouldn't individually have to find a sub for any time I was on holiday. But I'm really pleased I joined and it's a great way to get a bit of fun exercise with nice, like-minded people. And if you phone up, the people who organise it are helpful.

Well run, any issue has been resolved swiftly, great way to make new friends.

The league is great. We've really enjoyed playing. The pitch is great, refs are great and love the quick score updates online

We compete in multiple leagues as a team, doing multi-sport in the winter and then rounders in the summer for the last few years. I love it! I love the opportunity to experience different things and there is such a great balance between competitive and friendly fun. Would recommend.

I love playing with Go Mammoth it’s friendly fun and the best form of exercise for me as flys by. The refs are always lovely too! X

Something anyone looking for some community and a fun workout should ABSOLUTELY sign up for!

Great organisation

Signing up for Rounders was - whisper it - the best thing I did this summer. Despite my. having no hand eye co-ordination my team were friendly and welcoming. Communication from Go Mammoth was a little patchy in the run up but it all worked out fine and this is now my favourite addition to my summer. Playing rounders in Regents Park on a summer evening is an utter joy and I am so grateful to Go Mammoth for making it happen

Friendly teams, great umpires

I’ve given Go Mammoth every chance to address my concerns, but after reporting a poor experience and asking to be contacted, I’ve been ignored for the last few weeks. That silence speaks volumes about how little they value player feedback or safety.

The refereeing in their basketball league is beyond unacceptable. Instead of running a fair, recreational environment, referees behave in a childish and vengeful manner. Since the moment I questioned some of their calls, I’ve been targeted:

Inconsistent enforcement: Smaller players are allowed to play as physical as they want, but the second I match that intensity, I was ejected without warning after setting an illegal screen. Yes, it was a losing-my-cool moment, after multiple games of constantly being hit — certainly not something that justified being thrown out in such a dramatic way.

Embarrassing treatment: One referee literally stopped a game, forced me to leave the building, and sat on the scorers’ bench until I left. I left promptly so I wouldn’t delay the game or waste anyone else’s time, but the way it was handled was absolutely unprofessional.

Biased officiating: In the next game, I stayed silent for an entire half, only to be hit with multiple technicals the moment I objected to being hooked on screens. This is not refereeing — it’s personal vendettas disguised as officiating.

Disregard for player safety: When I calmly tried to speak with a referee after the game, expressing concerns about getting injured, his only response was “it’s a physical game” followed by a smirk. Yet when I play physical, I get called for offensive fouls or technicals almost every few possessions. So which is it? Physical, or only when it suits the refs?

But to be clear — this isn’t only on the referees. This is Go Mammoth’s failure. There is zero oversight, zero accountability, and zero interest in improving. They don’t care about players; they only care about sending automated emails and marketing spam. There’s no real feedback mechanism, no follow-up, and no attempt to resolve complaints.

I don’t work 50+ hours a week just to risk injury in what is supposed to be a recreational league — or to indulge the power fantasies of random referees who are completely unchecked by the organization.

And if you don’t have the slightest competitiveness in you, if you’re ready to accept nonsense calls, constant contact, and weeks of punishment the moment you lose your cool, stuck in a loop where you can’t talk, can’t fight back, and can’t reason — then congratulations: Go Mammoth is the perfect league for you.

I’ve been playing netball for a year now with Go Mammoth in Birmingham and it’s great! The umpires are always really friendly and you can tell they care about the games and players. I think that they should do some more marketing in the area as we don’t have many teams in the league at the moment and it would be more fun with more teams to play against :)

Despite the prices having risen considerably over the years I’ve played netball in London, Go Mammoth provides a great opportunity to meet new people and enjoy such a range of sports. I consistently recommend it to people and I do think it’s a great set up!

Go mammoth 5 a side at Blackfriars’s using city of london schools 4G pitch is a great league. Referees are fun and consistently good. The level is high recreational. Not for complete beginners but for anyone who wants a good run around. My only complaint would be the quality of the footballs. They’re often under inflated and just over warn. Also there aren’t enough of them at each game night.

DO NOT USE Go Mammoth. The leagues never start when they say they will. They will share your contact details without your consent and add you to leagues you did not consent to. Refunds are not dealt with in a timely manner. Communication is extremely poor and Cameron tried to blame me when I complained about receiving emails about a league I had been asked to be removed from. Avoid at all costs.

Such a great idea to have these fabulous games for adults to play in teams. Really fun, totally chill vibe, all welcome and really well organised.
