About this Unlimited edition

This edition has its own implementation, artwork and question bank. It is not affiliated with Krillion.io. It offers free repeat games, six themes and seven language interfaces. Scores are game-specific editorial tiers and personal browser records, not an official global leaderboard.

Unlimited means you can start another dive for free whenever you finish. The bank currently contains 210 prompts, with 35 in each of six categories. Prompts can repeat between games. You do not need an account, a subscription or a download.

The classic mix draws from geography, nature, science, food, arts and sports. A themed dive uses only one category. Try a relaxed dive without a timer while learning, then use the 25-second clock for a faster challenge.
