“Beyond Tetris — discover the joy of creation.”

Stack, Erase, and Create.

The history of block puzzles changes here and now.

Developed single-handedly by Japanese creator Nakamura, DELTARIS is nothing less than a revolution in falling-block puzzle games.

【About the Game】

DELTARIS redefines the classic falling-block genre as a brand-new style of puzzle RPG.

“Already mastered TETRIS?”
Then it’s time to experience DELTA FORCE — a groundbreaking system where placing blocks in special shapes automatically “creates” new ones that fill the gaps.
Every flash of insight can trigger massive chains and unleash thrilling attacks on your foes.

Forge a new chapter in puzzle history — through creation itself.

【Key Features】

● The Innovative “Delta Force” System

This isn’t just stacking blocks. By intentionally forming triangular gaps, new blocks called Delta Forces are automatically generated!
Plan, create, and dominate the field with strategic chain reactions unlike anything you’ve played before.

● Puzzle Meets RPG in Dynamic Battles

Clearing lines that include Delta Forces activates Delta Attacks, dealing damage to your enemies!
Face off against fairy-tale and myth-inspired foes, each with unique HP and abilities.
It’s not just about score — it’s about defeating enemies and progressing through stages for a true sense of accomplishment.

● Massive Variety of Game Modes

Enjoy a wealth of content: a full Story Mode, an Endless Mode that tests your limits,
over 24 Mission challenges, a logical Puzzle Mode, and exciting 2-Player Versus Battles for local play.

● An Epic Story to Save the World of Tales

In the sanctuary of dreams known as Castle Mugen, all stories are born.
But now, they are being corrupted by the mysterious “Dark Ink,” turning beloved heroes into demons.
Take on the role of Delru, the girl who inherited the Delta Force, and embark on an adventure with General Mikage the Cat to restore the purity of these lost tales.
