Gameplay

Plan your chains carefully

Domino tiles link together to form chains.

The longer the chain, the bigger the multiplier.

But careful placement can unlock unexpected combo paths.

Build a powerful upgrade engine

Upgrades dramatically change how scoring works.

Some reward specific tiles.

Others reward risky plays or clever combos.

Stack the right upgrades and your score can explode.

Tile modifiers change the rules

Special tile modifiers transform the board:

• Golden tiles boost scores

• Sticky tiles lock into place

• Other modifiers open new strategies

Every run evolves in unexpected ways.

House rules

House Rules are powerful modifiers that redefine how the game works.

They can:

• Change how scoring is calculated

• Add new effects to tiles

• Reward risky or unusual strategies

Stack multiple House Rules to create completely new playstyles.

The real strategy is not just playing well —

it’s building synergies that plays for you.

Combine:

• Upgrades

• Tile modifiers

• House Rules

…and watch your score spiral out of control.
