One move. Many consequences.

Easy to read. Hard to stop.

The rules take seconds. Mastering pressure, timing and the next perfect cascade takes much longer.

01
◆

Drop with intent

Choose a column and shape the board around the next runes in your queue.

02
ϟ

Connect three

Link matching runes. Gravity pulls the board together and can ignite a fresh cascade.

03
✦

Bend the chain

Prisms, bombs, lightning and volatile runes turn careful setups into spectacular clears.

04
⌁

Beat the pressure

The timer tightens, slag falls and anomalies force every run to evolve.

Ten arenas

The Forge never stays still.

New board silhouettes, colors, hazards and tactical choices arrive as your score climbs. Reach level 10 and the Ultimate Forge becomes your permanent arena while the difficulty keeps rising.
