    What is flash anzan?

    Numbers appear one at a time and vanish. You picture the soroban (Japanese abacus) beads in your head and keep a running total. Abacus schools around the world use it to train mental calculation. The speed and length in this game follow Soroban Kingdom's level table (20th Kyu: two 1-digit numbers at 1.5 s each, up to 10th Dan: fifteen 3-digit numbers at 0.3 s).

    Want to practice more?

    Soroban Kingdom has addition and subtraction on the abacus, multiplication, division and mental math for every level. Levels 20โ€“16 are free forever โ€” no sign-up. See also the level guide.
