Open Settings from the home screen. Every change is applied at once and saved with your profile; the name in brackets is the field in the save file.
Soroban
| Setting | Choices | Default | What it does |
|---|---|---|---|
Rods (rod_count) | 9, 13, 17, 21, 23, 27 | 13 (9 on a new Android profile) | Rods on the free-practice soroban and the upper limit for drills. Drills use fewer when the problem needs fewer, so beads stay large on phones. |
Beads move by (input_mode) | tap, drag, both | both | Tap moves a bead group in one go; drag lets beads follow the finger and snap on release. |
Show the number under the rods in free practice (show_numbers) | on, off | on | The digit under each rod. Drills decide for themselves: a “read” item hides them, anzan hides them. |
Show the on-screen keypad (show_keypad) | on, off | on | Items that need a typed answer always show it. |
Left-handed layout (left_handed) | on, off | off | Puts the keypad on the left. |
Hint after (hint_delay_seconds) | 1.5 to 10 s | 4 s | How long Abax waits after your last move before showing the next one in a drill. Guided practice in lessons always uses 1.5 s. |
Appearance
| Setting | Choices | Default | What it does |
|---|---|---|---|
Theme (theme) | system, light, dark | system | Paper and ink, or the dark variant. “system” follows the operating system. |
Finish (finish) | walnut, ebony, maple | walnut | The soroban’s material. Walnut: lacquered walnut frame, bamboo rods, bone beads. Ebony: near-black frame, brass rods and beam, bone beads. Maple: pale maple frame, steel rods, slate beads. Vermilion stays the one accent in all three. |
Large text (large_text) | on, off | off | Scales all text by 1.22. |
Reduce motion (reduce_motion) | on, off | off | Beads jump to their new place instead of gliding, and the hint halo stays steady instead of pulsing. |
Sound
| Setting | Choices | Default | What it does |
|---|---|---|---|
Bead click (sound) | on, off | off | A short synthesised click per bead group: a 2 ms noise burst into a decaying 1.8 kHz resonance, a little lower for the heaven bead. |
Volume (volume) | 0 to 1 | 0.6 | Loudness of the click. |
There is no sound on Android; the settings screen says so when there is no audio output.
Flash anzan
The three free-flash settings, digits (flash_digits, default 1), numbers
(flash_count, default 5) and seconds per number (flash_ms, default
1000 ms), are set on the flash screen itself before each run and remembered
there. See Anzan and flash anzan.
Data
- Profile shows the path of your save file.
- Save now writes it immediately (Abax also saves by itself within 5 seconds of a change, and when it closes).
- Reset all progress asks for confirmation, then deletes lesson progress, mastery and history. Your settings stay.
