Daily Halo

Daily Halo is a free browser game built around the cast of Blue Archive, the school-themed gacha game. Its page calls itself the Schale Database, after the office the player runs in the game, and greets you as Sensei. The site names Nova Drake as its author.

Each day one student is picked for everyone, at midnight UTC, from a pool of 136 playable students (alternate versions of a student are left out of the pool). You type a name into the search box, choose her from a list of portraits, and the game lays out how she compares to the answer: academy, role, class, attack type, defense type, height, age, rarity and school year. Matches and misses tell you which way to go next.

Wrong guesses unlock Arona's Hints, three pictures that narrow things down: the student's halo pattern after one miss, her weapon after two and her unique gear after three. Each field of a guess is green for a match, red for a miss and yellow with an arrow when the answer's rarity, height, age or year is higher or lower. You have 10 attempts in all, and a counter at the top shows how many players have already found today's student.

When the day's puzzle is done you can switch to an unlimited mode, labelled Archive, which deals out random students as many times as you like. The code is open on GitHub, and the result screen links to the game's Discord. It suits Blue Archive players who know the students by their schools and halos; someone new to the game will find the list of names long.
