Some days you don't feel like a study session. Now there's another way in: Tower Defense, a game that runs on the deck you're studying.
How it works
Open a deck and press Play Tower Defense. Enemies march along a road, and you have five spots beside it to build towers. Towers cost gold, and the only real way to earn gold is to answer questions from your deck.
- Each question gives you a few answers to pick from, usually four. Tap one, or press its number key.
- A right answer pays gold, and answering several right in a row pays a bit more.
- A wrong answer pays nothing, and shows you the right one. That card comes back a few questions later, so you get another go.
- Spend your gold on three kinds of tower, upgrade them, or sell them to rebuild somewhere better.
Hold the road for ten waves, with a boss at the end, and you win. Let too many enemies through and the run is over.
Defeating enemies earns a little gold too, but not enough to win by ignoring the questions. The cards are the engine of the game.
Made for learning, not just for speed
- Relaxed mode slows the action down so there's time to read every question. There's also a pause button, and you can play at 2x once you're confident.
- It works with a keyboard or a touchscreen.
- Sound is off until you turn it on.
- At the end, you see every card you missed with its right answer, plus a link straight back to studying the deck.
Does it count?
If you're signed in, a finished run counts toward your daily streak, and your score is the number of different cards you got right. A game can't earn more than a study session of the same deck could, so the weekly leaderboard stays fair.
Playing doesn't change your review schedule. Your spaced-repetition reviews still come from studying, so a quick, half-guessed game can't push a card further away than it should go.
You can play without an account, too. Your run just isn't saved.
Which decks work
Any deck with at least four questions. Multiple-choice cards are used as they are. Flashcards become multiple choice, with answers taken from other cards in the same deck. Cards with very long answers are left out, because they don't fit on a button, and the game tells you how many it skipped.
