Every game comes in three difficulties and three modes: a daily puzzle that is the same for everyone, an endless mode where difficulty climbs as you keep winning, and a marathon mode where you play on until three lives run out. The site is available in twelve languages, but the puzzles themselves are identical everywhere — digits need no translation.
