Gameplay
The gameplay is pretty similar to the original. Players break or mark blocks according to the number on their to show a 3D model. Rows with no necessary parts in them are marked with a blue zero while the other rows are marked by a number indicating how many in a row matter. This entry introduced the orange numbers, which are blocks that do not fill an entire block and/or curved whereas blue numbers indicate straight square blocks that are used. The game also introduced the bomb button which eliminates any 0 blocks on the outer side. The special challenges - Time, Construction and One Chance are returning from the previous game. This time, instead of being sorted by difficulty, the puzzles are scattered between themed 'books', and their difficulty is adjustable separately. Solving each puzzle rewards the player a gem. With the higher difficulty being selected and less number of mistakes made by player, a better type of gem would be rewarded; the best type is the rainbow colored one. Further books would be completing certain objective. Completing the first 40 books rolls the credits, with the other books serving as 'Extra' puzzles. Each 3000 points earned (collectively) adds a stamp on the save file, designed as a 'Membership Card'. There are 10 stamps at all, and collecting all of them loads a special message. The game also supports some amiibo figures, which scanning each will unlock a puzzle based on the scanned amiibo.
