0 views 0 plays

Jumlah Silang is a crossword made of numbers: every dark square gives the sum for the row to its right or the column below it, and players fill digits 1–9 without repeats until every sum adds up. Thirty levels span five worlds, Morning Paddies, Sunny Beach, Dusk Temple, Firefly Forest and Starry Sky, with boards that grow from 4x4 to 9x9 and always have exactly one solution. Uhu the owl mascot offers tips and praise, while a combination list and notes mode help newcomers without taking the challenge away from number-puzzle fans. Try it right here below, then picture a game like this featuring your brand’s logo, characters and prizes.
