mix 600ml water and 1 package jelly into a saucepan

heat over low heat, stirring constantly until boiling (add sugar if the jelly still not sweet)

put the first layer of biscuits into the mold (you can use marie regal biscuits or another round biscuits/wafers)

pour the jelly over the biscuits until the biscuis sinking, or its okay if the biscuits floating after that

refrigate the mold +- 5 minutes until the jelly start to set

repeat steps 3-5 with remaining jelly for a total +- 3 layers

after completing all the layers, refrigate the jelly overnight. To unmold, with clean fingers, loosen the jelly around the edges of the mold cavities. Place your serving plate on top of the mold and invert

and the last you can pour some sugar on the jelly for garnish, GOODLUCK ;)
