3C Arena: 3 Cushion Billiards

3C Arena is three-cushion billiards the way it is played on a real table: three balls, no pockets, and a point only when your cue ball finds three cushions before the second ball. The physics are simulated, not scripted — side spin, follow and draw, speed, squirt and even a raised cue all change the route, exactly as they do in the club.

PLAY ONLINE
• Private rooms: share a code and play a friend anywhere.
• Sitting together? Pass one phone between two players.
• Tournament rules: a 40-second shot clock, the equalizing inning, and penalty innings when a match ends level.

LEARN 31 DIAMOND SYSTEMS, STEP BY STEP
• The systems carom players really use: the 50 System and Five & Half, Plus and Maximum Plus, Reverse, 2/3, Kobayashi, Bernie, Sid, Conti, Easy Seven, Florida Backup, the Double Rail, the Ball System and the Mirror — with bank shots and routes out to the 4th and 5th rail.
• Every system in three steps: Learn it (diagram, formula, worked example), Practise it (real positions with the diamond numbers drawn on the rails) and prove it in a scored Challenge.
• The physics plays the shot, so you see exactly where the system holds and where speed and spin move it.
• The System Library: a reference catalogue of 34 systems, with the formula, rail numbering or calculator for each one that is documented. Free to read.
• The 50 System is free to play; one purchase unlocks every other system for good.

TRAIN AT YOUR OWN PACE
• Journey: 120 hand-made positions, from natural angles to five-rail shots, three stars each.
