Fifty is a flashcard drill for US geography. A card names a state, and you tap it on the map. It's the sibling of Clef: same deck-on-the-table feel, same idea that the misses should come back until they stick.
It runs right here on this site — free, nothing to install, nothing to sign up for. It works on a phone, a tablet, or a laptop.
Games
| Game | How it plays |
|---|---|
| Find it | The card names a state; tap it on the map |
| Name it | A state lights up and its shape is on the card; pick its name from four |
| Explore | Tap anything to hear its name, with the map shaded by what's been learned |
In Name it, the wrong answers are mostly neighbors, so it can't be won by knowing that Texas is big.
Settings
| Setting | Options |
|---|---|
| Region | All 50, or one of the four Census regions: West, Midwest, South, Northeast |
| Mode | Practice, or a 60-second sprint |
| Voice | Says each state's name, so kids who aren't reading yet can play |
Picking a region zooms the map in, which is also the answer to Rhode Island. On the full map, the five smallest eastern states get callout boxes out in the Atlantic, the way printed maps do it, and a tap within a fingertip of the right state's border counts.
What paper can't do
Missed states come back more often. Fifty keeps the last eight answers for every state in each game and weights the deck toward the ones you've been getting wrong. The worst are listed under States to work on, and Explore paints the whole map green for known, red for still learning.
Sprints keep a best score for each game and region. Progress lives in the browser on that device; nothing leaves it.
