Summer Splash Game Jam Roundup!

By The Code Zone team 2 min read

Our second, and final, Summer Game Jam is over, and we had so much fun! We've collected some of our favorite games that our members have worked on, keep reading to take a look!

Once again another excellent game jam has come and gone, and once again we’ve had so many wonderful submissions that we’d LOVE to share with you! Sadly we only have time for a few of these today but we’ve been absolutely stunned by everyone’s games this time round!

Summer Octo-Splash by Fraser

a title screen for a child's game, it has a dark green background and says "the code zone summer octo splash"

This game sees a retro styled octopus trying to collect loads of shells while avoiding sharks, starfish, and birds! When we lose we even get a really cool interactive title screen, big fan of the vibes on display here!

Summer Splash by Dylan

Dylan sets this game atop a grand water slide with multiple lanes, it’s our job to dodge all of the obstacles that appear as we slide down! How long can you survive without running into a dropped hat or a misplaced rubber ring?

Twisty Summer Splash by Nial

This fun and interesting twist on our base game gives us a new twist to the level every time we play! Maybe your dinosaur has gills and needs to enter the water to survive? Maybe there’s been a drought? Maybe the entire level is flipped on its head!

Summer Splash by Oliver

Oliver’s game starts with a fun little skit before taking us underwater with a diver trying to avoid rocks that float towards us! Rumor has it that there’s a special voice line that plays if you manage to stay alive for ten whole minutes!!

 

And that’s just a few of our favourite games from our most recent game jam! Hungry for more? Just head on over to the game jam tab and play these and more! 

How a game jam works

  1. Six to eight weeks of club

    An hour a week, the same mentor, a group of no more than six. Over a term the pieces stack up: events, loops, variables, functions, and whatever else the thing they are building turns out to need.

  2. Then the holidays, and a theme

    We announce a theme and stop there. No brief, no worksheet, and no deadline you can fail. It is the one stretch of the year with an unbroken run at a single idea, which is why most of the building happens here rather than in the term.

  3. Then somebody else plays it

    Finished games go up on our own platform and on this page, where sharing between members is moderated by mentors. Other children play them and award XP. Having a stranger pick up the thing you made is the part that keeps children coming back.

About our game jams

A game jam is a themed build: we announce a theme, and children across the clubs spend a few weeks making something from it. There is no brief beyond the theme and nothing to finish by a deadline you can fail. Children share what they made on our own platform, where chat and sharing between members is moderated by mentors.

Jams run alongside the ordinary weekly clubs rather than instead of them. A Game Dev Club session is one hour a week, in a group of no more than six, with the same DBS-checked, STEM-certified mentor each week.

Children build their own games rather than working through a set course, starting in Scratch or MakeCode and moving to Python and TypeScript when they are ready.

Past themes have included Evolution, Elemental Powers, The Wall of Doom and Strange Sports, and the results range from a two-screen platformer to something genuinely strange that only makes sense to its author. Both count. A jam is the one point in the year where the brief is deliberately loose, which is when children who normally follow instructions carefully surprise everybody.

Mentors write a note on every child after every session, which is how we know when somebody is ready to move up a level, or would rather stay where they are. Levels move down as readily as up, so the work always fits.

More than a third of our members are autistic or have ADHD, based on what parents tell us when they join, and in 2025 we received the Autism Inclusion Award from the National Autistic Society.

Children can keep the camera off, type instead of speaking rather than being put on the spot, take a break without it disrupting anyone, and step away and come back.

Jams tend to be where that matters most: a deadline nobody set and a theme nobody has to interpret the same way is a much easier place to take a risk than a classroom is.

Live clubs run online across the UK and in person across Essex, Hertfordshire, Cambridgeshire and Suffolk. Over 1,000 children are enrolled. In 2026 we were ranked second in the UK in Club Hub UK’s Top 100 Children’s Activity Providers, scored by five independent judges on safeguarding, inclusivity and community impact.

The blog is in two halves. Guides are the evergreen explainers written by the mentors who teach the clubs, covering the questions parents actually ask: what comes after Scratch, how to support a coding-mad child when you cannot code yourself, and what works for autistic and ADHD children.

Club news is the other half, and it is where posts like this one live: game jams, Minecraft builds and weekly roundups, written up by whoever ran the session. Neither is marketing. If you want to know what the work actually looks like before you sign up to anything, club news is the more honest read of the two.

The first session is a free taster and we do not ask for card details. Book a free taster session, see what it costs, or read about support for neurodivergent children.
