How SM-2 spaced repetition fits a Swedish word arcade

The SM-2 algorithm schedules the next review close to the moment you would forget a word. Failures return sooner; easy items stretch out. That keeps minutes of practice focused on what still needs work.

LearnSwedishFast ties those intervals into gameplay sessions so reviews feel like levels—not homework. You can start immediately on /play without signing up; optional accounts exist later for sync features described on /pricing.

Browse /words (with search) when you want to inspect pronunciation hints before you commit a word to high-speed recall. For the honest “first 100 rows” table from our dataset, see 100 essential starter words.
