Abako Daily is a free mental maths game: six numbers, one target to hit exactly with the four operations, each number used once — the same idea as the numbers round on Countdown, or NYT Digits, but as a daily. Four draws a day, identical for everyone, with no timer, no account and no ads. The solutions above are one possible route — there is almost always more than one, and comparing yours is half the fun.
