Evaluation
Sandwich Sudoku launched on August 19, 2019 with 40 hand-crafted levels. The store description explicitly promised "5 new levels every month for the first year (a total of 100 levels!)" — a clearly scoped, time-limited content plan. Developer news confirms the monthly update cycle was underway: new levels shipped on September 16, 2019, October 22, 2019, and November 21, 2019. Following that cadence, the full 100-level target would have been reached by approximately August 2020, completing the one-year update commitment. No announcements of content beyond that original plan have ever been made, and the last developer communication was on November 21, 2019. The game was designed and delivered as a finite puzzle collection, and the promised content cycle has long since concluded. No further updates, DLC, or ongoing development activity have been communicated by the developer.

About this game
Presented by Cracking The Cryptic, YouTube's most popular Sudoku channel, here is the brand new "Sandwich Sudoku" game that has become an internet sensation!
In Sandwich Sudoku, the puzzle is presented with extra numbers outside the grid next to each row and column. These numbers indicate the SUM of cells sandwiched between the 1 and the 9 in that row/column. The logic required to solve the puzzles will appeal to anyone who enjoys normal sudoku and a bit of basic maths. Each puzzle here has been lovingly hand-crafted by Mark Goodliffe and Simon Anthony, the hosts of Cracking The Cryptic. They've even included their own hints on each puzzle to help if you get stuck. Mark and Simon have both represented the UK many times in the World Sudoku Championship.
