Gemini 3 is indeed impressive. In my limited testing with it, it feels like it is able to take on larger, complex prompts with ease and low failure rate. I think one of the biggest strengths that Gemini 3 has is its ability to generate coherent looking 3D voxel... or SVG art, which makes it super easy to create game prototypes without having to implement art at all. Made this Heroes of might and magic-inspired overworld prototype with mini map and basic UI in less than 2 hours. Really excited to test this more. Demis Hassabis and Logan Kilpatrick and the Gemini team, you guys really cooked this time!show more

dude this looks EXCELLENT! any way you can provide a prompt or very short guide on how you built this? Would love to start a side project

Thanks Alex! My starting prompt is this: Create a heroes of night and magic game in threeJS in voxel style. Before creating it, write up a Game Design Document first. Basically it uses the GDD MD file it creates as a scaffolding on what to build next.

@AlexFinn Which IDE did you use for agentic workflow?

@enesdotid @AlexFinn I used cursor for this

@AlexFinn Thank you 🙏🏼 Is it one-shot output and is it show how many tokens it burned?

@enesdotid @AlexFinn I think it took about 20+ prompts, not sure how much tokens were used tho

Insane speedrun, Danny! Zero to playable HoMM overworld in <2h with Gemini 3 is next-level. Mind blown! 😍😱 Please look at my game that was coded via Gemini:

Thanks! Ronin’s rest looks pretty impressive!

Your opinion really means a lot to me and made me so happy. If you can, I'd love to hear your thoughts on this website, too. The one I built with Melis (@miilesus) using Vibe Coding in Gemini. 😍🫶

@miilesus Oh wow this is made with Gemini 3 too? It’s crazy good

Yeah, yeah! I make it with just one prompt. Here you are, dude. Hope you enjoy it. 😍 @miilesus, help me. > Create a bold and artistic portfolio website design in Neo-Brutalism style. High contrast black and white color palette with neon lime green accents. Massive, screen-filling typography, raw grid lines, and sharp edges. Retro computer aesthetic elements blended with a modern layout. Marquee scrolling text effects are visible. Brutalist web design, raw, edgy, and impactful.

@miilesus Thanks for sharing the prompt! I’m gonna try making some web design mockups with Gemini 3 to see how it performs

@miilesus Aww, sounds great, Danny! I'm waiting for that. Thank you so much for sharing your thoughts. It truly means the world to me. 🥹🫶

Love it! I built something similar

Wow that looks amazing!

Yeah I had a very similar experience. Excellent fidelity on graphics, models, placement etc - even within just a few iterations, getting something that looks pretty solid (lots more work needed on top)

amazing. i also tested the model and agree with most points.

One shot Unity + Asset Store is the new SOTA benchmark 😤

lol l’d love that

Grok + deepseek in one html file =

very cute!

Gemini 3 seems to handle complex, structured outputs like 3D voxel or SVG art with a consistency that really sets it apart from earlier models.

slop

Haha thats awesome, my first test of Gemini 3 was to make a HOMM3 clone as well. Didn’t turn out nearly as good as yours tho 😂

2 hours...... this feels illegal somehow

Almost lol

The speed here is what stands out. Two hours from concept to prototype is remarkable.. but what's more interesting is that you spent zero time on asset creation. This is the shift people are missing. The bottleneck in game prototyping has always been art production, even for simple concepts. If Gemini 3 can generate coherent visual assets on the fly, it fundamentally changes the iteration loop. You can test game mechanics without the upfront investment in visual design. The question is whether this holds up at scale. Does the coherence break down when you need variations, or can it maintain a consistent visual language across multiple assets?

I made these games too! Play Now! by DreamCore

amazing！！

This is awesome. I'm working on a game idea that would really benefit from this exact style. Could you share the prompt you used to get started?

Sure! Here’s what I started with: Create a heroes of might and magic game in threeJS in voxel style. Before creating it, write up a Game Design Document for this game first.

It's so simple 😂 Did you use Antigravity, CLI, Studio...?

Yeah it is, basically the GDD doc becomes the prompt for it to start building the game. I used cursor for this. Though I heard that Gemini 3 is even better in Anti gravity, so I might check it out!

I've messed around with Antigravity a little. It's impressive!

Wow

Beautiful work!

1 guy, 2 hours, impressive. A one man game studio.

Amazing!

Wow

Mind sharing the prompts/process?

Sure! Here’s what I started with: Create a heroes of might and magic game in threeJS in voxel style. Before creating it, write up a Game Design Document for this game first. Then ask Gemini 3 to use that GDD MD file as reference when building the rest of the game.

Looks awesome. Was that still with Love?

Oh this was made with threeJS

Oh I have tried this yet. I'll need to have a look. Is there anything on Patron for this?

Actually... I've just read your picking the right game engine post.

Awesome hope it’s helpful!

the coherent voxel/svg generation is the step that changes the game. when outputs are structurally valid AND aesthetically decent, the creative possibilities expand in a way that benchmarks can't measure

What an age we live in. Was waiting for a review from you on g3

Thanks Jake! Yeah it is an impressive model that I am keen to explore more.

It seems great with assets as you say! The websites it can 'oneshot' seems to edge out above sonnet 4.5 from my tests (still close, but its cheaper)

I need to try the website design on Gemini 3. It looks really impressive!

I really need to take its artistic abilities for a spin this looks great!

Thanks! Looking forward to see what you make

i went nuts and tried to hand this power directly to the player.

Nice. That’s actually a great idea for a game!

Looks dope Danny, will it be updated in Vibeforge ?

Yes! Im writing up a more in depth post on Patreon. Will be up soon!

It nailed all the voxel art? Super impressive.

Yes that’s what I’m most impressed about.

You should try to create a game for @hytopia people are building entire games with the AI powered tools provided by the team. Some people are attracting thousands of players everyday.

Are you gonna drop a tutorial?

I might if there’s enough interest! But here’s the prompt that I started with: Create a heroes of might and magic game in threeJS in voxel style. Before creating it, write up a Game Design Document for this game first.

Wow

I need to go play with that.

Love the graphics on this one Danny, and definitely seems like Gemini could be pretty stellar for game dev 🔥

It's also quite cool how gemini can generate multiple sprites or images with the same style, which is essential for making a game

this is so good bro!
