DEN DEN BLOCK
Telephone game, but you build with blocks. See a prompt, build it — the next player guesses what it is in one word, then builds from that word alone... then everyone watches the chain fall apart together. Somehow "cat" becomes "rice ball". Party madness for 3-8 players, online or on one shared PC.

About This Game

"What IS that?" is the highest compliment.


DEN DEN BLOCK is a party game of telephone played through block building. Prompts get more warped with every build — and the final reveal cracks the whole room up.

HOW TO PLAY

  • Build — see your prompt and build it in 90 seconds
  • Look — the next player sees only your creation
  • One word — they guess what it is in a single word and pass it on
  • The reveal — prompt → build → word → build... everyone watches every chain unravel together!

FEATURES

  • No waiting — everyone plays their own chain at the same time
  • 90-second chaos — you don't need to build well. Messy is funnier
  • Hidden guesses — one-word guesses stay secret until the reveal
  • Voting & awards — vote for the build that made you laugh and crown the Best DenDen Award
  • One-PC mode — gather around a single PC and play offline, pass-and-play
  • 10 languages — Japanese, English, Simplified Chinese, Traditional Chinese, Korean, French, German, Spanish, Portuguese, Russian

PLAYERS & MODES

  • Online: 3-8 players (create a room and invite friends)
  • One-PC mode: 2-8 players (offline, pass-and-play)
