In-game boosters are items that help you clear stages. You can get them in events and elsewhere.
They are used while playing stages.
• Miracle hammer damages pieces and gimmicks in the tile you select.
• Super splasher damages all pieces and gimmicks in the row you select.
• Crash drill damages all pieces and gimmicks in the column you select.
• Shuffle hands shuffle around all normal pieces and normal items.
Note: When you use in-game boosters, the number of moves doesn't get lower.
