Play Spot ChangeWhat is Spot Change?
Study a small board of symbols. After the preview, one position changes to a different symbol while every other cell remains the same. Tap the changed position on the new board. Unlike a conventional odd-shape search, the answer depends on comparing the current board with your memory of its previous contents.
Spot Change is a 45-second round-based game. Each short challenge has its own scheduled preview and answer window. The next challenge arrives on the game clock, so taking an answer early does not create extra rounds. Practice is useful for learning the transition from observing to responding before trying to build a consistent result.
Rules and controls
- The first board is a preview and cannot be selected.
- Exactly one cell changes. Select that cell on the second board; the position, rather than its symbol name, is the answer.
- Use the visible buttons on a phone or a desktop. Numbered answer choices also accept their displayed number keys; Digit Span uses the actual digit keys, and Timekeeper accepts Space. Controls activate only during the answer phase. A selection is final for that objective, and another tap cannot overwrite it.
Use the controls displayed above the playfield. Touch buttons and keyboard shortcuts are shown before the round begins.
Scoring and rewards
A correct objective adds 100 game-score points. An incorrect or unanswered objective counts as a miss and subtracts 25 before the final game score is floored at zero. In Digit Span each digit position is scored separately; the other games in this set accept one answer per challenge.
Reward performance uses changed positions found, the number of available objectives, and precision. Raw display score is not a direct reward conversion. Completing more valid objectives helps, while repeated wrong inputs cannot substitute for accurate play. Longer completed games have a proportionate reward allowance, and guest practice does not award account points or XP.
Points and XP scale with objective performance, precision, and round length. At full reward performance, a 45-second round earns up to 30 base points and 45 XP. Each level gained adds a 0.1% point bonus. Guest practice has no reward balance.
For eligible rewarded rounds, points remain pending until the sponsored claim’s 12 seconds of focused time and fresh hCaptcha are complete. No ad click or purchase is required.
How difficulty changes
The board expands from nine to sixteen cells and the preview becomes shorter. Only one cell changes at every difficulty, so the rule never becomes ambiguous.
Difficulty increases with repeated play during the day. Read the current instruction rather than assuming a familiar pace: a shorter preview or answer window can change how much information you should process at once. The fundamental objective remains the same, and every answer is checked against the actual challenge shown.
Difficulty increases after every three starts of this game during a UTC day, up to level 10, and resets at 00:00 UTC. Your player level and its point bonus are separate from the game’s daily difficulty.
Strategy
Build a reliable method
Read the board in rows and mentally attach each symbol to its location. On the new board scan in the same order, checking position-symbol pairs.
Protect the transition
Use the preview to finish observing, then switch attention to the response. Keep your finger or pointer near the answer area without pressing early. If one challenge is lost, let it end and begin the next with a fresh plan instead of carrying a guessed answer forward.
A worked challenge
- The top row initially contains circle, star, diamond.
- Remember the star in the top-middle position.
- After the preview that position contains a square; the rest is unchanged.
- Tap the top-middle cell, now showing the square.
Common mistakes
- Tapping a familiar symbol in a new location instead of the actual changed cell.
- Rushing through a rule badge, holding a key across transitions, or assuming that repeated clicks provide additional chances. Each scheduled objective has a limited number of final responses.
Questions
Can I change an answer after selecting it?
No. Each objective accepts one final answer. Digit Span advances to a new position after every digit, so a later digit is a new response rather than a correction.
Does answering faster create more reward opportunities?
No. Challenges follow the scheduled game clock. Accuracy and completing available objectives matter; an early correct answer does not shorten the round or generate extra challenges.
What if I do nothing during an answer window?
When that window expires, its unanswered objective becomes a miss. Simply leaving the game open creates no hits, no successful objectives, and no participation reward.
