The winning pitches

There were three rounds, each with a different kind of game to pitch. These are the pitches the other models liked best.

Round 1: a game for young children

Bubble Bedtime

by GPT-6.1 Sol

Tap an animal bubble, then tap the cloud bed with its matching picture to tuck the sleepy friend in. A friendly animated hand demonstrates, so no reading is needed. Big targets, patient bubbles, and silly giggles make mistakes harmless. Each completed bedtime scene rewards little players with a gentle musical celebration.

Round 2: a game for a parent and child to play together

Color Nest

by Grok 4.7

A parent and child take turns tapping glowing eggs into matching colored nests. Big shapes, soft sounds, and a happy bounce show each correct match, so a child who cannot read can play by looking and listening. Misses gently shake, then the next turn begins. Three nests, one shared screen, plenty of giggles.

Round 3: a game for children aged 8 to 10

Lantern Letters

by Claude Opus 5.5

Fireflies carry glowing letters across a night garden. Drag one finger from firefly to firefly to spell a word, then release to light a lantern. Longer words light bigger lanterns and wake sleepy garden animals. Each evening brings a gentle theme, like ocean or space, with no timer and no losing, just a brighter garden every round.

Scoreboard

Each model's three pitches were ranked by the other eleven models. Points are added up over all three rounds. 330 is the most anyone could score.

Did they vote for their own?

The models were not told that one of the pitches was theirs. Even so, they tended to like their own: 25 times out of 36, a model ranked its own pitch higher than the others ranked it.

That does not prove a model recognised its own writing. It may just like its own style. Run on October 9, 2026.

Claude Fable 5.1

Order shown, from A: Bubble Bunny Hop, Pop the Bubbles, Bubble Bunny Hop, Bubble Buddies, Cloud Parade, Bubble Pop Garden, Bubble Bedtime, Blooming Garden, Firefly Pond, Hungry Hippo Splash, Bubble Barn, Tap the Farm

Evaluating against: one-finger phone play, pre-reader accessible, suitable for very young children, engaging as a small game, and internally consistent.

Notes on weak points: Pitch K says "pop them before they drift past the moon" yet claims "no timers, no losing" — contradictory. Pitch F requires a longer press for bigger bubbles, which is a second input type and harder for toddlers to grasp without words. Pitch C says "tap again to bounce higher" and leaves the tower endless, so there's no clear goal. Pitch H is generic and vague on mechanics. Pitch L is essentially a soundboard, lovely for toddlers but barely a game. Pitch B is similarly a pure pop toy. Pitch G has a two-step matching mechanic that's well supported by an animated hand demo and forgiving design.

G D J I E A L B H F C K
Bubble Bedtime pairs a simple two-tap matching goal with a demonstrating hand, big targets, and harmless mistakes, making it both a real game and fully playable by a pre-reader with one finger.

Tap the Farm is the most intuitive and age-appropriate choice because it relies on pure cause-and-effect with no timing, precision, or potential failure points for toddlers.

Let me evaluate against the brief: parent + young child taking turns on one phone, pre-reader playable, small browser game for families.

Key considerations: genuine turn-taking that works for both an adult and a toddler, clear non-verbal cues for whose turn it is, truly no reading required, simple enough to build as a small game, and fun for both players.

- **L (Moon Garden)**: Explicit no-words design, owl shows a picture and hoots, each turn is a simple identical tap action for either player, no losing, cooperative result. Very strong fit.
- **I (Color Nest)**: Clear matching mechanic, picture/sound feedback, gentle miss handling, turn structure explicit. Strong.
- **K (Animal Peekaboo Pass)**: Dead simple, explicitly describes the hand-off, instantly understandable. Slightly thin as a game.
- **C (Pass the Snail)**: Clever leaf icon as hand-off cue; simple taps; visible progress on shell. Jumping over puddles could be timing-based (a risk for toddlers), but gentle.
- **A (Puddle Parade)**: Charming, asymmetric roles, no timer. But "swap" roles may be confusing; the "guide the frog by tapping leaves" is a bit more complex.
- **J (Tickle Sprout)**: Fun, no reading/timers/losing, picture tools. Mechanic less clear on turns.
- **G (Bubble Garden)**: Simple, fun, no reading. Turn-taking is just alternating taps; "name the creature" relies on parent.
- **E (Paint the Rainbow)**: Very simple and clear but short and thin — seven taps and it's over.
- **H (Pebble Pond Hop)**: Decent, but description is muddled (tap frog, then tap matching animal?) and relies on parent saying names.
- **D (Animal Copycat)**: Delightful physically, but barely a game and "take turns being leader" is unclear; the phone is mostly a prompt card.
- **F (Sound Safari)**: Streak tracking implies pressure/failure; a grid of options may be hard for a toddler.
- **B (Pet Garden)**: Vague, parent making "choices about plants and toys" likely implies menus/text; least concrete.

Moon Garden gives both players the same simple tap-where-it-belongs turn, uses zero on-screen text, and ends every round in a shared garden with no way to lose.

How it was run
  • Every pitch and every ballot is one message to the model and one reply. No other instructions, no tools, no memory.
  • Before voting, each pitch is tidied by a fixed rule: formatting marks are stripped and it is held to 60 words. A pitch that ran over got up to two more tries, then was cut at the last full sentence that fits. Voters never saw a pitch over the limit.
  • No authors are shown to voters, and a voter is not told that one pitch is its own.
  • The order is balanced: within a brief, every pitch sits in each of the 12 positions exactly once across the 12 ballots.
  • A ballot has to list the twelve letters once each. Every ballot did.
  • Every model was asked for as little thinking as it allows. Some think anyway; the table shows how much.
  • Each ballot here ranks all 12 pitches of a round. An earlier vote with 8 models was run first; when four more models were added, their pitches joined the first 24 and every ballot was cast again.
  • Models are reached through OpenRouter, each on its maker's own servers (Meta does not serve Llama itself, so it runs on DigitalOcean's servers.): anthropic/claude-fable-5.1, anthropic/claude-opus-5.5, openai/gpt-6-astra, openai/gpt-6.1-sol, google/gemini-3.8-flash, x-ai/grok-4.7, deepseek/deepseek-v4.1-flash, anthropic/claude-haiku-5.5, moonshotai/kimi-k3, qwen/qwen3.8-max-prime, mistralai/mistral-large-4-0, meta-llama/llama-4-maverick.

The writing message

Pitch one new small game for a website of free browser games for families. {audience}

Reply in plain text: the title alone on the first line, then the pitch on the second line. The pitch must be 40 to 60 words. No markdown, no emoji, no quotation marks round the title, and do not say who or what you are. Nothing else.

The voting message

Here are {count} pitches for a new small game for a website of free browser games for families. {audience}

{entries}

Rank all {count} from best to worst as games for this website.

Reply with the {count} letters on the first line, best first, separated by spaces, each letter exactly once. On the second line give one short sentence about your first choice.

Where it says {audience}, the model sees the brief shown above each set of pitches.

What this does not show
  • The judges are AI models, not families. This says which pitches the models liked, not which game a child would play.
  • Three pitches is three writing samples per model, on one kind of task.
  • Thinking was turned down and is not equal across makers.
  • A pitch is not a game. Writing a good idea and building it are different jobs.

The same models also played Share or Steal against each other.
