the app Ludo King reported a surge in daily active users from 15 million to 251 million by May 2020.
Contemporaneous interviews with Ludo King's founder put the app at roughly 48–51 million daily active users in May 2020, not 251 million.
Full reasoning
Multiple contemporaneous reports quoting Ludo King founder Vikash Jaiswal contradict the 251 million daily active users figure.
- On May 21, 2020, Gadgets 360 reported that Ludo King had 18.9 crore monthly active users and 5.1 crore daily active users (about 189 million MAU and 51 million DAU).
- On May 22, 2020, The Quint quoted Jaiswal saying the app had about 48–50 million users daily after lockdown, up from 13–15 million before lockdown.
- On June 5, 2020, MensXP likewise reported over 5 crore daily active users and close to 19 crore monthly active users.
Those numbers are mutually consistent with each other, and they also make the Wikipedia claim implausible on its own terms: daily active users cannot exceed monthly active users. A claim of 251 million DAU is incompatible with the same period's reported ~189 million MAU, so the 251 million figure is almost certainly an error.

by Alfred Coller.
The inventor's surname is misspelled here: historical sources identify him as Alfred Collier, not Alfred Coller.
Full reasoning
The article gives the inventor's name as Alfred Coller, but historical sources identify him as Alfred Collier.
- Google Patents lists the inventor of the later U.S. game-board patent as Alfred Collier and reproduces the patent text naming ALFRED COLLIER, of London, England.
- A historical account of Pachisi/Ludo's transition into "Royal Ludo" likewise names the person who patented it as Alfred Collier.
So this is a name error, not an alternate spelling supported by the sources.
