Vaults

Defend the vaults with towers, crack logic locks mid-battle to power them up, and fill a museum with rare relics.

Rune Slide

Slide whole rows of Elder Futhark runes, chain cascades and pick your path through a branching map of puzzles, shrines and markets.

Play Rune Slide

Firewall

Drag your turret left and right, shoot down bugs and malware, grab patches and dodge viruses. Eight waves, then the Rootkit.

Play Firewall

Spell Hive

Trace words across a honeycomb, fill the witch's pyramid, brew the cauldron and wake the hidden word.

Spark Stack

Falling blocks where every full row is a lock cracking open. Chain cascades, charge the Overload and play it offline.

Play Spark Stack

Hunt

A bug hides in every colour zone. Find them all with logic: never the same row or column, never touching. Three lives.

Play Hunt

Spark Clicker

The original: tap, build generators and solve logic locks for surges. Daily Race and a shareable Daily Code.

Play Clicker

Spark Boxes

Dots and boxes on squares, triangles and octagon boards. Draw a line between two dots, claim a shape and go again.

Play Spark Boxes

Sort Lab

Three quick puzzle modes in one place: pour coloured liquid into tubes, time your taps on a ring road, and slide blocks to free the ferret.

Play Sort Lab

Bug Lanes

Lane defence: bugs crawl in along five lanes and you spend energy on defenders to stop them before they reach your core.

Play Bug Lanes

Whispers of Wonderland BETA

A minesweeper-style delve through the fog: read the numbers, light the lantern and find your way down, floor by floor.
