Accountants
Arithmetic at the speed of the source document, with the audit trail intact.
Accounting is arithmetic plus pattern recognition plus episodic memory. The skill that distinguishes a good ledger is not how fast you add, it is whether the row that does not look like the others jumps off the page.

Why these games
Math keeps the in-head arithmetic so automatic that the eye is free to scan the row that does not match. Sequences trains the pattern-of-numbers instinct · monthly variance, seasonality, the run-rate that drifts. Memory Game protects the audit-trail recall · who entered what and why, three weeks later.
