A game you might find familiar, yet uniquely arranged with the charm of Gensokyo.
Enjoy a new kind of puzzle battle with friends and players from around the world!
Pieces made up of 4 blocks fall from above (with some exceptions).
Arrange them to fill horizontal lines on the field—when you complete a line, it disappears and you earn points.
Once you accumulate enough points, you can attack your opponent!
Attacked players receive incomplete lines from the bottom, gradually filling up their field.
When your field is completely filled to the top, you lose.
If you manage to fill up your opponent’s field to the top, you win!
And there’s more...
Use "Skills" to gain the upper hand!
Each character has unique skills that can clear the field, send strange pieces to your opponent, flip the field upside down, and more!
Skills charge up as you clear lines or as time passes. Use them wisely to control the game!
For beginners new to clearing lines, a Mission Mode is available.
You can learn different ways to place, clear, and master puzzle techniques according to specific conditions.
For advanced players...
There are also special training modes that cannot be seen in normal play.
Other exciting modes include:
"Survival Mode": Defeat one opponent, and the next one appears! Keep winning to see how far you can go!
"Spin Relay Mode": A time attack mode requiring special techniques to clear all 6 challenge types.
"Endless Trial Mode": Like Mission Mode, but it continues endlessly. Clear as many tasks as you can under given conditions.
...and many more modes await you!
Not only can you play against CPUs, but also enjoy 2-player matches!
There are over 10 unique stages, each with special gimmicks.
Combining these stages with different characters creates new and exciting ways to enjoy the game.
When the online servers are open, you can battle players from around the world.
Show off your skills to top players worldwide!
In Story Mode, the characters of Gensokyo engage in lighthearted battles using this mysterious puzzle game that has arrived in their land.
There are storylines for all 22 characters!
Each character will face off against 3 designated opponents to unfold their unique story.
By meeting special conditions, a 4th opponent might appear, or unexpected battles may occur, offering small but fun changes to the story.
Try different approaches and see what surprises await!
A game where lining up blocks horizontally clears them—a familiar concept—
has somehow entered Gensokyo.
In a land still trapped in the eras of Showa and Heisei, this game naturally becomes a huge sensation.
Of course, in Gensokyo, original rules emerge,
blending in the Spell Card rules to create a serious puzzle competition.
And as always, where there's disturbance, there's resolution.
Now, witness the daily lives of Gensokyo's strongest with your own eyes!
