Rift Riff

Rift Riff is a strategic tower defense game in which you jump through rifts, fight monsters and plunder their worlds. You choose a set of towers for each scenario, then build them on predetermined spots to defend your Extractor, your main tower.

Defend each rift

Monsters attack in waves. Some head straight for your Extractor, while others attack every nearby tower. You earn juice, the resource used to build, during waves, and can build or upgrade towers before and during each one. Surviving the attacks earns prisms, which unlock more rifts, towers, companions and tower upgrades.

The game makes setbacks forgiving: you can schedule a tower when you lack the juice to build it, get a full refund for a tower you built by mistake, and have a lost tower respawn for free after the wave. If your Extractor falls, you only need to redo the last wave, and picking flowers provides extra juice.

Worlds and challenges

The full game offers approximately 15–20 hours of gameplay, with:

• 20 worlds, each with at least two scenarios.
• 17 tower types and 7 overpowered upgrades.
