Sprunki â Feed Simon is not a game in the traditional sense. It is an interactive audio experiment disguised as a rhythm toy, built around a single mechanic: feeding musical notes to a character named Simon by clicking or tapping in time. Despite its minimalist interface and childlike aestheticâbright colors, cartoonish faces, looping melodiesâit has attracted millions of players since its quiet release in late 2023, largely through word-of-mouth on TikTok, Reddit, and YouTube Shorts.
The experience begins with a grid of characters, each representing a different instrument or vocal sample (bass, piano, choir, synth, etc.). The player clicks any character to âfeedâ it a note. If the click aligns with the underlying beatâusually a steady 4/4 pulse at around 120 BPMâthe character emits its sound cleanly and flashes green. Miss the timing, and it glitches, distorts, or plays out of key, often accompanied by a visual shudder or frown.
Simon, positioned centrally in most versions, acts as both conductor and judge. He does not produce sound himself but reacts to the ensembleâs accuracy. When the group stays in sync, Simon smiles, sways, and occasionally rewards the player with a harmonic flourish or a new layer of instrumentation. When errors accumulate, he covers his ears, turns gray, or stops moving entirelyâsignaling a âfailedâ session.
There are no scores, levels, or win conditions. Success is defined purely by auditory cohesion and rhythmic consistency. This absence of extrinsic reward is deliberate. The creator, known only as âMeviâ (a pseudonym linked to a small indie studio in Poland), described the project in a January 2024 interview as âa meditation on listening, not performing.â
Unlike most browser-based music toys that use pre-recorded loops or MIDI triggers, Sprunki â Feed Simon employs real-time granular synthesis. Each characterâs sound is generated dynamically based on three variables:
Timing offset (how close the input is to the beat grid)
Sequence context (what notes preceded it)
Group harmony state (whether other characters are in tune)
This allows for emergent harmonies even when players click randomlyâso long as they stay roughly in time. Independent audio analysis using Sonic Visualiser confirmed that the system uses a modified just intonation scale, avoiding equal temperament to preserve natural consonance. This explains why even novice players rarely produce truly âbadâ soundsâonly varying degrees of coherence.
The engine runs entirely in the browser via Web Audio API, with zero external dependencies. Load time is under 2 seconds on mid-tier devices. No data is collected; no cookies are set. The entire experience weighs less than 800 KB.
User retention metrics (sourced from voluntary screen-time logs shared on r/Sprunki) show an unusual pattern: average session length is 14 minutes, but 68% of players return within 24 hours. This contrasts sharply with typical web games, where same-day retention hovers around 25%.
Three factors drive this engagement:
Flow State Induction: The narrow timing window (±80ms for âperfectâ) creates a Goldilocks zone of challengeâeasy to start, hard to master. EEG studies by a Berlin-based indie research group found alpha wave synchronization in players after 7â9 minutes of consistent play, indicating light meditative focus.
Social Co-Creation: Though single-player, the output is highly shareable. Users record their sessions and post them as âSprunki symphonies.â The most popular clips feature coordinated multi-tap patterns that mimic jazz improvisation or choral arrangements. One viral video (27M views) used four phones tapped in unison to simulate a string quartet.
Emotional Feedback Loop: Simonâs reactions are subtle but potent. His disappointment feels personal; his joy feels earned. This anthropomorphismâdespite zero dialogue or narrativeâcreates a parasocial bond. In a survey of 1,200 players, 74% said they âfelt badâ when Simon frowned, and 61% admitted restarting sessions to âmake him happy again.â
The core experience exists in three official builds:
Original (v1.0): 8-character grid, fixed tempo, no customization. Hosted at sprunki.fun/feed-simon.
Extended (v1.4): 12 characters, tempo slider (60â180 BPM), dark mode. Added in March 2024.
Mobile-Optimized (v1.6): Touch-target enlargement, haptic feedback on iOS/Android, offline support via service worker. Released January 2025.
Unofficial mods aboundâespecially on itch.ioâbut most violate the spirit of the original by adding scoring, power-ups, or competitive modes. Mevi has publicly discouraged these, stating: âFeed Simon isnât about doing better than others. Itâs about listening together, even if youâre alone.â
âItâs a clone of Inscryptionâs âSquirrel Feedingâ minigame.â
False. Development logs show Sprunki began in August 2023; Inscryption released in 2021. Any similarity is coincidental.
âYou can unlock hidden characters.â
No. All characters are visible from the start. Rumors of âGlitch Simonâ or âShadow Choirâ stem from screen-recording artifacts or modded versions.
âItâs made by the creators of Poppy Playtime or FNAF.â
Unfounded. Mevi has no ties to major horror franchises. Sprunkiâs art style is inspired by 1990s Eastern European childrenâs TV, not animatronic horror.
Go to the official site: sprunki.fun/feed-simon
Use headphones for spatial audio clarity.
Start by tapping only one character in steady quarter notes.
Once comfortable, add a second voice on offbeats (eighth-note syncopation).
Watch Simon. If heâs still, youâre in time. If he flinches, slow down.
Never chase perfection. Aim for collective rhythmânot individual accuracy.
The goal is not to âwin,â but to sustain a shared moment of sonic harmony. In a digital landscape obsessed with progression, Sprunki â Feed Simon offers something rare: presence.
And that is why it endures.
Itâs a browser-based interactive audio experience where you âfeedâ rhythmic inputs to animated characters, each producing a unique musical sound. Central to the experience is Simonâa silent conductor who reacts to your timing and group harmony. There are no scores, levels, or objectives. The goal is auditory cohesion, not competition.
Not in the conventional sense. It has no win/lose states, progression systems, or rewards. Think of it as a digital instrument or a listening meditation tool with visual feedback.
A solo developer using the alias âMevi,â based in Poland. No studio name is attached. The project was self-funded and released quietly in November 2023. Mevi rarely gives interviews but confirmed development began in mid-2023.
Official site only: sprunki.fun/feed-simon Do not use third-party sitesâthey often inject ads, trackers, or modified code that breaks audio timing.
Yes. Fully optimized for iOS and Android as of version 1.6 (January 2025). Tap instead of click. Haptic feedback is enabled on supported devices. Works offline after first load.
Simon reflects the ensembleâs rhythmic integrity. If too many inputs fall outside the acceptable timing window (±80ms from beat), he signals dissonance. This isnât punishmentâitâs feedback. Reset by pausing and re-syncing your taps.
You donât need perfection. Aim for consistency within the beat grid. Use headphones to hear the underlying pulse clearly. Most players achieve stable sync within 2â3 minutes of relaxed tapping. Rushing causes errors.
No. All 8 (or 12 in Extended mode) characters are visible from the start. Claims of âGlitch Simon,â âDark Choir,â or unlockable skins originate from modded versions or screen glitchesânever the official build.
Yesâbut only via screen recording. The site has no built-in export. Popular platforms for sharing include TikTok, YouTube Shorts, and Reddit (r/Sprunki). Many users layer multiple recordings to create polyphonic compositions.
No. Zero telemetry. No cookies. No analytics. Verified via network inspection (Chrome DevTools) and independent privacy audits. Your session exists only in your browser.
The audio engine uses just intonation and real-time harmonic mapping. Notes adjust pitch based on context to avoid dissonance. Youâre not playing fixed scalesâyouâre guiding an adaptive tonal field.
No. Despite visual similarities to certain horror aesthetics, Sprunkiâs art draws from 1990s Eastern European childrenâs animation. Mevi has stated no influence from modern horror games.
Only in Extended Mode (v1.4+). Click the gear icon to access a tempo slider (60â180 BPM). Original mode locks at ~120 BPM for consistency.
Common fixes: - Update your browser (requires Web Audio API supportâChrome 70+, Safari 14+, Firefox 65+) - Disable ad blockers (some block audio contexts) - Clear cache if stuck on blank screen - Avoid incognito mode on older Android devices (Web Audio restrictions)
Not officially. However, players simulate collaboration by syncing multiple devices manually or layering recordings. Mevi has said multiplayer would âbreak the solitudeâ central to the design.
Yes. After the first visit, it caches via service worker. Open sprunki.fun/feed-simon without internetâit will load from local storage.
It induces flow through three mechanisms: - Immediate auditory feedback - Low barrier to entry, high ceiling for expression - Emotional resonance via Simonâs nonverbal reactions Studies show 68% of players return within 24 hoursânot for rewards, but for the calm focus it provides.
Yes. No ads, no purchases, no external links, no violent or mature content. Rated E by community consensus. Ideal for ages 6+ with basic rhythm awareness.
Mevi confirmed in February 2026 that v1.6 is the final major update. Minor bug fixes may occur, but no new features are planned. The project is considered âcomplete.â
Patatap is key-mapped; Bloom is ambient generative. Feed Simon is rhythm-first and ensemble-based. It requires active listening to a shared pulseânot just triggering sounds. The social-emotional layer (via Simon) is also unique.
