⚡Flash Anzan Test & Training

How Flash Anzan works

Numbers appear one at a time. Keep only the running total in mind. When the sequence ends, enter the final total with the keypad or your keyboard.

Test and Training

Test keeps the selected number size, sequence length, operations, and flash speed fixed. It gives no correctness feedback during the session. Training shows the complete sequence and correct total after every answer. Adaptive Challenge can change the next problem based on consecutive performance.

Challenge settings

• Number Size: choose 1-digit, 2-digit, 3-digit, or Mixed 1–99 numbers.
• Numbers per Problem: choose 3, 5, 7, 10, or 15 flashes.
• Flash Speed: choose from 1.2 seconds down to 0.15 seconds per number.
• Operations: use addition only or add subtraction. Subtraction problems are generated so the running total stays positive.
• Problems: set any session length from 5 to 30.
• Adaptive Challenge: Training only. Two correct answers in a row move to the next genuinely harder number-size/speed combination; two incorrect answers in a row move to the next genuinely easier combination.

Flash Score and ranks

Each correct answer earns more difficulty-weighted points when the number size is larger, the sequence is longer, or the flashes are faster. Flash Score normalizes those points to a 15-problem equivalent, so ranks are comparable across 5-, 15-, and 30-problem sessions.

• Getting Started: under 60
• Novice Calculator: 60–149
• Steady Adder: 150–199
• Skilled Calculator: 200–549
• Advanced Anzan: 550–899
• Expert Anzan: 900–1499
• Anzan Master: 1500+

Training tips

• Keep only the running total in mind instead of trying to remember every flashed number.
• Increase one challenge dimension at a time when practicing manually, so you can tell what is causing errors.
• If accuracy drops sharply, reduce the challenge until the running total feels stable again, then build back up.

Results

Both modes show Flash Score, rank, accuracy, correct answers, best streak, average answer time, and a full problem review. Training also reports the fastest flash speed and highest number size completed correctly, plus the challenge progression from the first problem to the last.
