Hibi

From the App Store Source

one puzzle a day. one target between 100 and 999. six source numbers — four small, two large. six lines to reach the target exactly using +, −, ×, ÷. hibi is a maths game in the spirit of countdown's numbers round, distilled into a daily ritual that takes about as long as it takes to drink a coffee. the same puzzle for everyone, every day. solve it in three operations or five — there's no clock, no leaderboard you can grind, no level system. one puzzle, one verdict, one slow reveal of the target. one a day hibi shows you a target and six digits each morning. the puzzle is the same for everyone. solving in fewer lines is better; using fewer operations is better still. take your morning, the train, the lunch break — there is no clock. six lines reach the target exactly using +, −, ×, ÷. each digit can be used once per line. you have six tries. each line submits an equation, sees its result against the target, and the row tells you "low", "high", or "close" — never the answer. the puzzle is over when you hit the target or run out of attempts. on a loss, hibi reveals the optimal solution it generated for the day. practice not in the mood to commit to today's? practice mode generates a puzzle on demand at three difficulties: three operations (easy), four (medium), or five (hard). off the streak books, off the clock.
