Name of a variant of Four 4s ?
[edit]There are some games that propose the player an initial number, a goal number, some available operations and the amount of maximum operations. The player then needs to reach the goal number through a combination of the operations given.
For example. One has the operation "+9", "x2", "8->4" (a digit that is an 8 becomes a 4), a starting value of 0, five operations at most and a goal of 24. The solution is: "+9" (current value 9), "+9" (current value 18), "8->4" (c.v. 14), "x2" (c.v. 28), "8->4" (c.v. 24) .
How is such a game called? Pier4r (talk) 22:19, 3 January 2023 (UTC)
