I make Fillup, a tabletop-inspired browser strategy game based on Chain Reaction. You fill cells with pieces and set off reactions that capture neighboring cells.
This video starts with a recorded Campaign finish, then takes a look up the Tower scenes. There's an alchemy-themed tower, a lighthouse, an overgrown tower, and a haunted one. The future themes are labeled as previews.
They're part of the new Weekly Tower mode: a solo climb with checkpoints, cosmetic rewards, and harder ascents after the base ten floors. The game also has Campaign and local/online multiplayer.
It's free in desktop and phone browsers. You can try the main game as a guest; Weekly Tower requires a free registered account.
