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. • Daily Shot: one new position every day. • Play the computer at four levels, from Easy to Pro. • Practice on a free table: place the balls, replay the point, study the line. MAKE THE TABLE YOURS • Earn coins as you play and spend them on tables, cues and ball sets — including high-contrast balls. MADE FOR CAROM PLAYERS • Precise aiming: a fine-adjust dial, a strike-point pad for spin, a power slider and a contact preview. • Top-down and behind-the-cue 3D views, with instant replay of every point. • No account needed: open the app and play. • English, 한국어, Tiếng Việt, Türkçe, Español, 日本語. Whether you call it three-cushion, carom, carambole or 3-ball billiards — find your angle and master the game. 3C Arena is free to play. Coins and the Learn unlock are optional in-app purchases.
