Mental Math Speedrun · rules

Admin rules decide how questions are generated. Edit operand ranges, per-template weight, and enable/disable — changes go live within ~60s, no redeploy. The op is fixed (code owns the math); you configure the registered skill.

Back to stats

Weight sets how often a skill is drawn (higher = more frequent; blank/0 = default 1). Status live ⇄ retired toggles the template in/out of the live rotation. Ranges bound the operands the generator draws. Use Preview 5 to eyeball the spread before saving.
