What is Ease Hell?
Ease Hell is a phenomenon in Anki where a card's "Ease Factor" drops so low (usually 130%) that the interval between reviews grows painfully slowly. Even if you press "Good", the card comes back very quickly.
This creates a vicious cycle: seeing the card too often makes it annoying, but because the interval is short, you might press "Hard" again if you are fatigued, keeping the Ease low.
Signs You Are in Ease Hell
- You see the same cards every single day for weeks.
- Your "Young" card count is exploding while "Mature" cards stagnate.
- You dread doing your reviews because they feel like a treadmill.
The Root Cause: The "Hard" Button
In the default Anki algorithm (SM-2), pressing "Hard" multiplies the current interval by 1.2 (usually) AND permanently decreases the card's Ease factor by 15%.
Do this a few times, and a card that started at 250% Ease drops to 130%. At 130%, a 10-day interval only becomes 13 days. At 250%, it would have become 25 days.
How to Fix It
1. The "Reset" Method
The nuclear option is to reset the scheduling information for the affected cards. This treats them as new cards. It's painful but effective if the card is truly "stuck".
2. Use the "Straight Reward" Add-on
There is an Anki add-on called "Straight Reward" that automatically increases the Ease of a card every time you press "Good" on it. This slowly rehabilitates cards that have fallen into Ease Hell.
3. Analyze Your Deck with Penziv
You can't fix what you can't see. Use our Anki Deck Analyzer to identify exactly which cards have an Ease factor below 150%. You can then create a filtered deck in Anki to specifically target and fix these cards.
