Project Babel

Under the Red Moon, Open the Void Diary

Enter fogbound Veldhaven and follow the confessions and torn diary pages. Piece together the stories of those who came to the confessional and discover what happened there.

Place Your Blocks. Answer the Whisper.

Plan your placements, rotate pieces and clear lines. You may also answer the Elder God's whisper by copying the prayers that appear. Complete a prompt to restore Sanity, lift the current piece's curse and receive its blessing rewards. You may call it a prayer, a curse, or an act of defiance. But are these names the truth of your power, or explanations woven from your own fear and longing? Even your resistance may be the prayer it wanted to hear. Work Fire, Purification, Piercing and Shield runes into your plans, and find a way through with T-Spins, all clears and combos.

The Trials: Over a Hundred Challenges

Make a wild map of your own or take on someone else's. Try puzzles built around precise placements, refine a speedrun route, or raise the Heat with Oaths. Mutation mode changes the rules and gives you a reason to rethink a familiar board.

Compete on Global Leaderboards

Race for the fastest clear, solve a map with the fewest pieces, rack up a result within a time or piece limit, or see how long you can survive. Follow the objective and scoring rules of each map, improve your personal best, and compare results on maps that support rankings.

Silence Is Also a Choice

Some story sections require typing to progress. Trials and ranked runs let you skip it and clear objectives through placement, rotation and line clears.

The Elder God wants an answer. You may leave its words unfinished and press on through placement, rotation and line clears alone. In runs that use typing and Sanity, locking a piece with an unfinished prayer costs Sanity. Faster falls, more curses and uncertainty follow. Without the respite of prayer, the board grows harsher. But does enduring its pressure mean you have refused its bait? Obedience may offer no rescue, and silence may offer no freedom. Perhaps the more certain you are of your defiance, the deeper you have stepped into its design.
