Aim the cue: the dotted line shows where the cue ball goes, the ring is the ghost ball (where the cue ball will be when it hits), and the short line shows where the object ball will roll.
Mouse: point at where you want to hit. Press, pull back towards you and let go to shoot: the further you pull, the harder the shot. The mouse wheel or ↑↓ fine-tune the aim.
Keyboard: ←→ aim (hold Shift for slow), hold Space to build power and let go to shoot, S spin, C change the called pocket, Esc pause.
Phone: drag on the table to turn the cue (tap to point it somewhere), then pull the power bar down and let go to shoot.
Controller: the left stick points the cue, the right stick or L1/R1 fine-tune it. Hold ✕ to build power and let go to shoot (○ cancels). □ opens the spin picker, △ changes the called pocket, Select picks the cue ball up when you have ball in hand. Start pauses.
Spin: tap the white ball in the cornerpress □. Hit low for draw (the cue ball comes back), high for follow, left or right for side spin that bends it off the cushions.
8-Ball: pot the 1–7 (solids) or 9–15 (stripes), whichever you sink first, then the black 8 to win. Pot the 8 early and you lose! 9-Ball: always hit the lowest number first; whoever pots the 9 wins. 10-Ball is the same with ten balls, and the 10 wins.
Challenges: the Daily Rack is one 9-ball rack for everyone each day: clear it before the 90-second clock runs out (100 a ball, a time bonus for clearing, −50 for a scratch). In Pot Streak one ball appears at a time; pot it in one shot or the run ends. Both have leaderboards.
Fouls (potting the cue ball, missing, or hitting the wrong ball first) give the other player ball in hand: they can put the cue ball anywhere.
Win coins on the Pool Tour, in matches and from medals, then spend them in the Pro shop on cues, cloths, ball sets and upgrades like Pro Sight, which shows where the cue ball will go.
