Prime squares

Research output: Contribution to journalReview article


An overview on designing a puzzle with prime squares was presented. A latest game on playing with prime was proposed. A move in tic-tac-prime consists of placing a single digit in an empty square of a three-by-three grid. When one player's digit completes a segment of digits in a line, that player gets a point of each three digits prime that includes the last-placed digit.
