How to delete an actor BP with a specific variable value

I made a 2048 game in this video, how can I erase specific numbers such as 2, 4, 8, 16, etc. with the player’s key input?

so i guess you don`t have there character like BP_third…, if i understand correctly for example when player press down you want to do slowly animation then delete object and do number bigger for example from 2 and 2 to 4. in blue print you can get keys up,left,right,down then on press them do animation in animation you can use cinematic animation something like that and move objects together then you can use destroy actor 2 times for first object and for second one then create branches for bigger number or do math logic get number then if it is valid like 2 and 2 is valid 2 and 4 is not, * multiplay number by 2 then create or spawn object i guess is cube with output number.
