Game description (written by KoiArcade)
King Of Boxer is a colourful pixel-art boxing game. You read each rival's moves, dodge heavy punches, jab and cross when their guard opens, and fire a charged Super Punch to swing a round. There are 12 challengers spread across three circuits. Win the three championship belts and you face Iron Mike Dyson at the end.
Later fighters give you less time to react, so timing the interrupt when the guard is open matters more as you go.
How to play
- DESKTOP J Z Jab K X Cross.
- A D or larr rarr.
- Dodge left or right Hold W uarr Block normal punches.
- Space Super Punch when charged P Esc Pause.
- MOBILE Use the on-screen buttons.
Tips
- Watch the rival before you swing. A punch while their guard is open interrupts the attack and is safer than trading blows.
- Dodge with A/D (or arrows) instead of holding block forever. Block only stops normal punches; heavy hits still need a sidestep.
- Save the Super Punch for a clear opening. Wasting it while they are guarded leaves you stuck in the recovery.
- Each later challenger reacts faster. Short, clean combos beat long reckless strings.
- On mobile, use the on-screen buttons the same way: jab, cross, dodge, block, then Super when the meter is full.
