Limited Undo Connect-the-Dots

Detailed Description: Includes four colors, each with three endpoints (a total of 12 endpoints). The endpoints are complexly distributed. Players can use the “undo” function (up to 3 times). Lines cannot cross. A 2 minute 30 second time limit is set. Once the undo attempts are used up, no further undoing is possible. After four incorrect attempts, the game must be restarted, improving the player’s decision-making ability and concentration.
