For Self-Learners
Park Progression
The complete game system — bricks, building tiers, the pickaxe energy track, streaks, XP, visitors, and snoozing.
Everything in the park is earned by one action: answering review cards. Here’s the full economy.
Bricks & building tiers
Correct answers earn bricks for the card’s building. Buildings upgrade at:
| Tier | Bricks needed | Visitors attracted |
|---|---|---|
| 1 · Common | 0 | 10 |
| 2 · Rare | 200 | 50 |
| 3 · Epic | 1,000 | 200 |
| 4 · Legendary | 3,000 | 1,000 |
A Legendary building is a real achievement — it represents months of retained knowledge, not a lucky afternoon.
The pickaxe energy track
How many bricks a correct answer earns depends on your pickaxe, which reflects how consistently you show up. Your energy score runs 0–20:
- +1 energy for each day you complete your reviews.
- −2 energy for each missed weekday. Weekends don’t drain — rest is allowed.
| Pickaxe | Energy | Bricks per correct answer |
|---|---|---|
| Wood | 0–3 | 10 |
| Stone | 4–7 | 12 |
| Iron | 8–11 | 15 |
| Gold | 12–15 | 18 |
| Diamond | 16–20 | 20 |
Streak multiplier
Consecutive active days multiply your brick earnings on top of the pickaxe:
| Streak | Multiplier |
|---|---|
| 7 days | 1.2× |
| 14 days | 1.5× |
| 30 days | 2× |
| 90 days | 2.5× |
Missing one day doesn’t break a streak — there’s a one-day forgiveness built in. A 30-day streak with a Gold pickaxe means 2× × 18 = 36 bricks per correct answer.
XP & levels
Separately from bricks, you earn XP for activity: saving new learning (+20 base, +10 per concept), correct reviews (+15), even incorrect reviews (+5 — showing up counts), finishing your daily reviews (+50), and tier-ups (100 × the new tier). XP drives your learner level. Repeated saves in one day earn diminishing XP, so the system rewards steady learning over binge-saving.
Snoozing
Life happens. You can snooze up to 3 buildings — their cards pause without penalty. Use it for the course that’s on hold, not as a permanent mute.
Classroom assignments
Assignment buildings from a classroom work identically — same bricks, same tiers, same streaks. School work literally builds your park. They come with a building your teacher picked — fun fair, science lab, or garden — that changes look at every tier, and students get 4 designs to give it their own look (see Doing Assignments). New assignment cards arrive at most 10 a day.
Building designs
Self-learner buildings start as a construction site and need a design before they can be placed. You get a one-off bundle of 10 designs; each one generates the art for a building at its current tier. Designs are the only thing in SkillPark that does not renew — everything else is earned by answering.
