Use the four earlier accident years to choose an age-to-age loss development factor (LDF). Pick a historical or benchmark factor—or type your own—then reveal the observed value. Closer on a ratio basis earns more points.
Data & scoring
Paid tracks claim payments; incurred combines payments with case reserves. The highlighted cell is known and the question mark is held back until you pick.
Despite the playful title, each question asks for one age-to-age factor—not development beyond the triangle's oldest maturity. Each pick scores 0–100 using proportional error.
The game uses historical insurer-group triangles distributed through CASdatasets; amounts are shown as supplied, without an asserted unit while the local build provenance is reconciled.
