乗車案内 / Your boarding guide
Find a word.
Power the train.
Reach the Mount Fuji viewpoint in five rounds. You have 30 seconds per round, and rarer, longer words take you farther.
- Begin your ride. A short, untimed first-visit guide uses separate practice letters. Finish or skip it to depart. Practice awards no points and uses different letters from the playtest rounds.
- Make one word. Type on your keyboard or tap the letter tiles. Submit a valid English word of 3–7 letters, using each shown letter at most once. Delete removes the last letter; Clear starts the word again.
- Submit to boost. Your first valid answer locks immediately and earns its journey award. You do not have to wait for the timer. An invalid word costs no points; edit and retry while time remains.
- Keep riding. A 4-second celebration leads automatically to the next round. A timeout awards no points or distance and also moves you on. Complete all five rounds, even if you arrive early.
What moves the train?
Your word’s rarity tier supplies the base points below. Add two points for each letter beyond four, up to the existing 120-point round limit. There is no bonus for typing faster.
| Tier | Points |
|---|---|
| Common | 10 |
| Uncommon | 20 |
| Rare | 40 |
| Epic | 70 |
| Legendary | 100 |
| Kiseki · 奇跡 / Miracle | 120 |
Each earned point advances the route by one kilometre until you reach 450 km. Your distance then stays at the viewpoint while your score can continue toward 600. Length adds a bonus, but it does not by itself guarantee a higher rarity tier.
The demo uses corpus-based estimated rarity, rather than measured player choices. Very low-frequency or missing corpus entries are capped at Epic. See the sources and limitations.
Your replayable playtest
Replayable demo: the homepage uses the same five rounds on every ride. Replay freely; demo results do not contribute to daily counts.
Help, sound, and sharing
Use How to play in the game to reopen the guide before or after a ride. During a round, it shows quick rules while the timer keeps running. Sound is optional, and animations adapt to your device’s reduced-motion setting.
After all five rounds, copy your results or save and share the train ticket. The exported ticket includes your score, distance, tiers, and arrival status, leaving out your answers and letter racks. Sharing and photo-saving options depend on your browser and device.
