The toy and the method solve technical problems in the prior art. The memory-exercise jigsaw toy and the use method for the same comprise a base with a storage trough, wherein a first display module is disposed inside the storage trough; multiple block groups with different colors are placed on the first display module; each block group comprises multiple block bodies which have the same color and are in one-to-one correspondence with a colored display area; a sensing structure which can sense position information and/or color information of each block body is disposed in the base; the sensing structure is connected to an MCU module; and the MCU module is connected to a second display module which is disposed on the upper end of the base and used to display random color information synchronously with the first display module. The toy and the method provided by the invention have the advantages that the structure is simple; game modes can be switched at will; the toy is very interesting; the age scope of users is expanded; and players' memory can be exercised.
