Learning Games with Pets
Eight 3D pets for children aged 3 to 11, led by the FLYER mascot Bingo, and eleven games that connect them to FLYER vocabulary lessons, mini tests and Cambridge mock tests. One game is playable now.
Key facts, origin and limits
Proposal for discussion
Written on 02/10/2026 in reply to: "Dùng model tốt nhất để build các bạn pet 3D mà trẻ em từ 3 tuổi đến 11 tuổi sẽ thích, và đề xuất các games phù hợp với app học và luyện thi của FLYER https://roadmap.flyer.vn/pet".
Drafted by an AI assistant in a single session. It is a proposal for the product team to discuss, not a decision.
Sources:
- Homework submission rate of 49.9%: teacher.flyer.us read-replica, 19/09/2026, published in the Assignment 2.0 PRD.
- The Bingo AI app already ships a WebView component (react-native-webview), noted from the mobile-study repository on 27/09/2026.
- Cambridge Young Learners task formats for Starters, Movers and Flyers, as described in the public Cambridge English handbooks. Recalled for this draft, not re-read.
- The demo uses Three.js r186. Every model is generated in code; no third-party art or model files. Bingo is modelled from the FLYER mascot artwork and badge sheet supplied on 03/10/2026.
- Voices: ElevenLabs, model eleven_multilingual_v2. Sally (young, British) for Bingo and the 3+ and 6+ pets; Charlie (young, energetic) for Draco and Bolt. 108 clips, 2,018 characters, generated on 03/10/2026.
Limits:
- No sessions with children yet. Appeal by age band is an assumption to test.
- Effort sizes (S, M, L) are rough estimates.
- Frame rate on low-end Android phones is not measured. The demo was checked in a desktop browser and at a 390 × 844 phone size, with zero script errors.
- The ten food words should be checked against the current Pre A1 Starters wordlist, and Cambridge part numbers against the current handbooks, before content work starts.
- Baselines marked "to measure" in Rollout do not exist yet.
- Progress is saved on the device only; account sync is not built.

2What every pet does
| Child | Pet |
|---|---|
| Moves a finger | Eyes and head follow it |
| Taps the pet | Hops or spins, hearts, a short recorded English line; the mouth moves while it talks |
| Rubs the pet | Hearts and a purr; happy ring fills |
| Drags the background | Pet turns around, then faces the child again |
| Feed | Starts Feed me the word |
| Play | Dance, spin or hop; costs energy; yawns when tired |
| Sleep | Lights dim, eyes close, Zzz; tap to wake |
| Dress up | Party hat, bow, cap; crown and glasses are earned |
Three rings show food, happiness and energy. They drift down slowly and stop at 20%; a pet never leaves or gets ill.

1Fair play for learning and test prep
| Rule | Reason |
|---|---|
| No pet inside a timed test section | Practice conditions must match the real exam |
| Rewards follow effort, weighted by accuracy; improvement also counts | Weaker learners still progress |
| Rewards are looks only: hats, colours, rooms, evolution | No shortcuts and nothing to buy |
| No loss: mood floor at 20%, no illness, no leaving | Loss mechanics distress young children |
| A wrong answer names what was tapped | Each miss becomes one more exposure |
| Two misses highlight the right answer | No dead ends for non-readers |
| Cap on rewarded repeats of one game per day, e.g. 3 | Learning time over farming time |
| Audio first below age 6 | Most cannot read yet |
| Grown-up links behind a press-and-hold gate | Children stay inside the app |
| Parents and teachers see words learned, not only stars won | The report is about learning |
1Phases
| Phase | Scope | Where | Effort | Pass when |
|---|---|---|---|---|
| 1. Pilot | Feed me the word with real lesson words; Bingo, Mochi, Bao, Kiko | Bingo AI app, one school | 2–3 weeks | Children reopen it unprompted three days in a row |
| 2. Core | Paint my pet, Letter treats, Pet room; all 8 pets; Snack boss on mini tests | App and study.flyer.us | 6 weeks | Lesson minutes per child rise; accuracy holds |
| 3. Speaking and exams | Odd snack out, Spot the difference, Pet story with AI scoring; Expedition; Class pet | Exam room and Teacher app | 8–10 weeks | Mock-test completion and homework submission rise |
