ZOMDLE

The main ZOMDLE puzzle is a Zombies map, numbered and dated each day. You type any Zombies map name, and a row shows how it compares with the answer across seven columns: map, game, studio, storyline, crew, setting and year. Each attribute is marked correct, partial or wrong, and arrows show whether the year is higher or lower. You have six guesses, and the box holds 66 maps from Treyarch, Infinity Ward and Sledgehammer. The day's map is drawn from that box by the date, so a map can come round again within a few weeks.

Other modes have their own daily answers. Photo asks which map a screenshot comes from, Quote asks which character said a line, with the map as a bonus guess, and Trivia gives a question about the games in three attempts. Music plays a clip of a Zombies track that grows longer with each wrong guess or skip, from a fraction of a second up to fifteen seconds. Most modes can spend a guess on a clue, and each has an endless version, with Arcade for back-to-back maps. Race mode lets you create a ten-round photo or quote room and race friends by room code.

Yesterday's map is shown at the top beside a countdown to the next one. An optional free account saves streaks across devices and puts you on a global streak leaderboard. The site is fan-made, not affiliated with Activision, shows Google ads and asks for support through Ko-fi. It suits Zombies players who know their maps by name, crew and year.
