Crocobet

A chalk ring shrinks around every tennis ball that lands on the court, and your job is to strike the exact moment it touches the ball's edge. Hit it on the dot and the court flashes ACE inside Crocobet; mistime it and the ball drops away as a miss.

🎾 FOUR STROKES, ONE THUMB

Flat: A single tap on the ball

Topspin: A quick double tap

Slice: Swipe in the direction of the arrow beside the ball

Lob: Press and hold, then release as the ring meets the ball

Every stroke is graded ACE, CLEAN, EARLY, LATE, or MISS, and each grade is worth a different number of points in Crocobet.

🏆 THE CLUB TOUR
Eight fictional clubs stand on a single ladder, from Wicker Park Juniors all the way up to the Bluewater Invitational. Each club plays a three-set match (first to two sets) with its own tempo, set target, and mix of balls. Win a match to climb one rung and reveal that club's rival card, complete with a captain quote. Finish the top rung and a fresh season starts with quicker balls and higher targets.

⚡ QUICK MODES

Quick Rally: An endless run where three misses end it; the pace rises every ten balls and fresh ball types join along the way.

Daily Drill: One date-based challenge per day, such as Slice Only, Double Tempo, or Corner to Corner, with a 7-day streak to keep alive in Crocobet.

🧵 THE STRINGER WORKSHOP
Every match pays Felt, an in-game play currency. Spend it on six string setups that genuinely change your timing — a wider Clean window, a slower first ball, easier lobs and slices — or on cosmetic court surfaces such as Clay Rose, Lawn Mint, and Night Indoor.

📊 MATCH DIARY & STATS
Every match, rally, and drill is saved to a diary with lifetime Aces, tour win rate, a 14-day points chart, and accuracy for each ball type, so you can see your timing sharpen over the weeks.

🎨 STYLE AND COMFORT
Bright hard-court colors, bold outlines, crisp sound effects, and light haptics. A short tutorial with a practice court teaches every stroke before your first match. Settings include sound, vibration, a left-handed layout, and a reduce-motion option.

Chalkline Tennis is a single-player arcade game that works fully offline. All clubs, players, and results are fictional, and Felt is earned only by playing — it has no real-world monetary value.
