Scoring language
A personal best is the highest score this browser has stored for one game. A streak is a count of consecutive successes—made shots, matched pairs, or fruit slashes—that often adds a bonus until a miss resets it. A multiplier increases the value of later successes; it is not extra lives. Points describe the current round. Coins and XP on this site are local play markers with no cash value.
A run is one continuous attempt until lives are gone or the board is cleared. A session is the sitting that may contain several runs. Mixing those words is how people accidentally promise themselves “one more game” and play ten.
Space and timing
A hitbox is the actual collision shape, which may be simpler than the art. If you died and the sprite looked like it missed, the hitbox still overlapped. Leading a target means aiming where it will be, not where it is. A decision window is the time you have to act before the situation expires—pipe gap, falling orb, or sliding floor.
I-frames, if a game uses a brief post-hit invulnerability, are a recovery courtesy, not a license to charge through hazards. Most BrainBounce titles simply reset the immediate layout after a lost life so the next decision is clean.
Puzzle language
A chain or combo is several merges or pops that happen because one clear creates the next. Board health is how many useful options remain; a high score on a dying board is often luck. A well in Block Drop is a reserved column for a long piece. Toggling in Lights Out means a press that flips a cell and its neighbors; pressing twice cancels.
Using the same words as the guides makes practice notes shorter. “I lost board health chasing a chain” is a better lesson than “I messed up.” Precise language is a tool, not a test.
