Daily calc: every day played in a row extends your streak, shown on the home page with your last seven days and the time left before midnight.
Achievements: four new achievements for 5, 10, 50 and 100 days in a row on the daily calc, and a title to unlock, “Metronome”.
Dungeons: a full-screen countdown comes before each fight and the boss, then the fight shows on its own, with the calculation at the top of the screen.
Dungeons: chests are rarer but give two items and points, and the winner chooses who gets each item.
Dungeons: your bag stays visible in every phase, and tapping an item opens its card to use it, give it or drop it.
Daily calc: times impossible for a human are now detected, and cheating accounts are removed from the leaderboard and from online play.
Stats: a calculation left unanswered now counts as a mistake in your accuracy.
Version 1.3.0
Dungeons: set off on an expedition with 2 to 4 players, by invitation or with a code, across a map of rooms on four floors, then face the boss together.
Dungeons: twelve enemies to defeat with your calculations, chests (beware of mimics), a two-item bag, lives, and the chance to revive a fallen ally.
Achievements: new dungeon achievements and two titles to unlock, “Adventurer” and “Scourge of the dungeons”.
Dashboard: your stats by difficulty (games, accuracy, average time, online wins, best streak), filterable by game.
On mobile, the site loads faster: fonts are now served directly by Calculus.
Fixes: the new-version banner no longer shows on your very first visit, and online, rejoining a game with the same account no longer removes you by mistake.
Version 1.2.0
Daily calc: five calculations from Easy to Legend, the same for everyone, one attempt a day and a daily leaderboard.
Achievements and titles: unlock achievements as you play and pick the title shown under your username from your profile.
Online: if your connection drops, the site reconnects you automatically and you get your place back in the game.
Lobby: the buttons to start or leave stay at the bottom of the screen while you set up the game.
On mobile, a game now starts at the top of the screen, with no header or footer.
Fixes: in solo on a phone, the correction is full width again, and “Next” no longer triggers by itself after tapping OK.
Version 1.1.0
Solo: after a mistake, the right answer stays on screen until you move on to the next one.
On mobile, the keypad stays docked at the bottom of the screen and each key reacts as soon as you press it.
Online speed race: a 4-second pause between rounds to see who scored and the right answer.
Games page: a “Play solo” button for each game, which picks up your last settings.
Home page: the warm-up has its own title, and on mobile the two main choices come first.
Text lines up better with the grid paper, and your light or dark theme now stays in place when you switch languages.
This what’s new page: the version number shows at the bottom of the page, and a banner announces each new version for 48 hours.
