Champdle

Champdle fills a Connections-style grid with League of Legends champions. The featured mode, Quadra, shows sixteen champion portraits that hide four groups of four, and you pick four you think belong together. Each day brings a Lore board (regions, species and backstories), a Visuals board (looks, weapons and outfits), a Mechanics board (kits, crowd control and resources) and a Mixed board that draws on all three. You have four hearts for mistakes, a shuffle button and a hint button.

Imposter is a newer daily round. It lists five champions, opens each one's passive and four abilities, and one icon in every kit belongs to another champion. You get one tap per champion to find it, so a day's score runs from 0 to 5.

The build modes test a different kind of knowledge. Precision reveals a full item build and asks you to name the champion fast, and Detective gives one clue at a time until you work it out. They have their own leaderboards, and the site publishes meta reports with item, rune and lane data for each champion. Community boards made by players, and a tool to make your own, give you more to play once the dailies are done. The same site also runs Quadra boards for Dota 2 heroes.

It is a fan site, not endorsed by Riot Games, and it carries ads, including a small video player in the corner of the screen. No account is needed. It suits League players who know the roster beyond their own mains.
