What are Series?
Series are special training sessions outside of the main course, each with a different goal: raw speed, endurance, your weakest letter combinations, or holding out without making mistakes. They unlock as you progress through the levels.
Available series
| Series | What it trains | Unlocks at |
|---|---|---|
| N-Gram Master | Your weakest two- and three-letter combinations | 3 levels completed |
| Speed Run 200 | Raw speed on a short text | 8 levels |
| Marathon 1k | Endurance: two themed texts, about 1,000 characters in total | 15 levels |
| Survival | Accuracy under pressure: no deleting, 3 lives | 18 levels |
Plus, the Daily Warm-up: a short text that reviews exactly the keys you struggle with the most, with no speed requirements. Completing it gives you double experience for the rest of the day.
One thing to watch out for: except for the warm-up, the series use the entire keyboard, including letters you might not have seen in the course yet. This is on purpose: they are advanced training. To review within your own alphabet, use the Daily Warm-up.
