■Game Introduction
In this cute mascot puzzle game, players aim for the high score by launching, lining up, and growing the colorful Vacc-Balls that contain young vaccines. The more you collect, the higher your score and greater your level!
Play as much as you want for free, and earn customizations for your lab by competing in online battles and making the High Score Ranking.

■Basic Play
When you line up 3 or more of the same Vacc-Ball vertically, horizontally, or diagonally, the vaccine inside will grow. Open new levels and increase your score by collecting more and more.
When the screen fills to the top with Vacc-Balls, it's game over.
But game over isn't the end! If you have the special "MidoRich" vaccine, you can restart your game at the same level and score. #1 on the High Score Ranking can be yours!

The Battle Nutrients on the right side of the screen will fill up as you create chains of 2 and 3 and clear them. The Nutrients are ready when it's full!
You can now play in Battle Mode.
With Battle Mode, go head-to-head in 3 rounds against your opponent, filling the Attack Gauge with your color to win!

Also, you can use these 3 items to get yourself out of a pinch!
Item 1: Slow - The rate at which Vacc-Balls drop is slowed for 1 minute
Item 2: Clear - Forces the most numerous type Vacc-Balls in the field to grow
Item 3: Unlock - Destroys locked Vacc-Balls
Remember that you can only use 1 item per level.

MidoRich, Battle Nutrients, and in-game items can all be bought with Vac-Coins.

■Lab Decorations
Every week, the top player on the High Score Ranking will receive a present such as customizations for their lab or battle comments.
The #1 players on Monthly and Seasonal Rankings will also receive special presents, so don't miss either of these opportunities!

■Compatibility
Recommended for iOS 5.0 and newer.
The basic game is free, but purchases of in-game currency (Vac-Coins) require separate charges.
Because this is an online game, an internet connection is required.
