Your board has no duplicate entries, but nine cells are still blank. That is not a completed Sudoku. A second bug appears when a reset erases the…

The snake turns Down, then Left before the next tick. It has reversed through its own neck even though each key looked legal when it arrived. Another…

The player guesses L in BALLOON. Two positions should open, but only one letter was guessed. Another player enters Z twice with different…

The ball passes the right paddle, the left score rises, and the next animation frame awards the same point again. The drawing looks like Pong, but the…

The piece lands correctly, but clearing two rows leaves one behind. Or Hard Drop locks a piece and the next gravity callback locks it again. These bugs…

A queen appears on the destination pile, but it still exists in the source array. The screen looks plausible until a second move reveals two copies of…

You press a button while the sequence is still flashing, and the game counts it as your first answer. On the next attempt, a correct pair of presses…

A player attacks the same occupied square three times and the ship sinks without its other cells being hit. The interface has counted events instead of…

The character hits the underside of a platform, becomes “grounded,” and jumps again in midair. Or touching a side wall freezes the vertical motion. A…

A record says 1 calorie, but the converter never asks which calorie definition it uses. Another accepts 250 kW and reports joules as though a duration…

A word problem gives 25 mL of component A in a final solution volume of 200 mL. Dividing by 175 mL gives about 14.285714%, but that is not the requested…

A record says “1 hp,” but converting it to kilowatts gives different answers depending on what horsepower means. Mechanical horsepower, metric…

You enter −2² and expect −4, but the calculator shows 4. Then sin(30) gives a number unlike 0.5 because the site is using radians. A scientific…

The points are (−2,1) and (1,5). Adding the horizontal change of three to the vertical change of four gives seven, but the straight-line distance is…

You open a nested JSON record and see “007,” false, zero, and null. If the viewer drops false-looking values or turns the identifier into a number, the…

A student reads (42°N,102°W) as a generic x,y pair and chooses the wrong row. Another reverses the numbers and tries to enter 104 as latitude. A…

A team hands you the right code, but nobody can explain where one digit came from. Another team solved the tasks correctly and assembled its code in the…

You finish a course and mark the goal complete, but the next client handoff still says Send the draft soon. Attendance shows that a resource was used.…

One traveler withdraws from a four-person trip, so someone reduces the entire estimate by 25%. That removes part of a group transfer and part of a room…

An enemy reaches the endpoint on the same update that removes its last health point. The prototype awards a coin and removes a life. Elsewhere, an empty…

The dashboard shows three open orders with unfulfilled work and labels eight units Ready to ship. One order still has a pending payment. Another order…

A rook can move horizontally, so your board lets it travel from e2 to f2. But that rook was blocking a line of attack against its own king. A board that…

A held key keeps applying an upward impulse, so the flyer never falls. Another prototype gives two points for passing the upper and lower halves of one…

Player B reaches 20 on the turn display, and your game announces victory. But those points are still provisional: a one would discard them, and Hold has…

The schedule adds up to an hour, but Speaker 2 has no evaluator. Table Topics ends, and nobody knows whether to return control to the Toastmaster or…

A request fails, and the page says No records yet with an Add button. A user types zebra, gets no matches and concludes the source is empty. Both…

The follower hesitates when the leader changes direction suddenly. An observer calls it poor acting, even though the pair never agreed on a comfortable…

The diagram shows eight players, but the setup sheet asks for nine chairs. Row 2 is labeled entirely B even though one assigned player belongs to…

The timer ends, but the observer cannot tell whether five ordered cards count as success or partial credit. The next learner begins with sorted shapes…

At 1:50, the hour hand is close to 2. If you leave it pointing exactly at 1, your angle calculation uses the wrong position before you even compare the…

Your cover looks right on screen. After folding the paper, it lands on the back, and the preparation checklist appears after the instructions. The six…

A learner writes 24 ÷ 6 = 4 correctly, then builds four trays containing six tiles each. That model fits one situation, but it does not fit a request to…

A learner submits an allowed word, but the route uses the same cell twice. Another writes CAT while pointing to cells that spell CAX. A classroom…

Two learners write bear for the animal category. Both answers fit the letter B and the category. If the review marks them wrong because they match, it…

The redirect works, but the notice stays visible on the next visit. Or a test calls the flash helper twice inside one request and expects the second…

You change a route from notes to entries, but the template still contains /notes/7/. The page renders a plausible-looking link to the old location.…

You have a viscosity value of 12 and need another unit. One source says cP; another asks for cSt. A converter that treats both as alternate labels for…

Your worksheet says “5 in 125,” and a calculator returns 4%. That answer is incomplete until you know what the two quantities measure. Five grams in 125…

You enter 4% and a molar mass, but the calculator asks for density. Which one: the solution's density or the solute's? Leaving that distinction out can…

Your data contains three records, and the build folder contains three pages. That sounds right until two records share an ID, one page contains another…
