What is Plain Daily Game?
Plain Daily Game is a browser game about getting close to a number. Each daily flight contains seven rounds: five ask you to name something with a value near a target, and two ask you to estimate a number. You might compare country populations, explore the solar system or test your knowledge of chemical elements. You do not need a perfect answer to score. A sensible estimate can keep your plane climbing.
How to play Plain Daily Game
Read the target and its unit
Open a round when you are ready. Read whether it asks for a name or a number, then check the unit. A country with a population near 48 million is a different challenge from a country covering 48 million square kilometres. The timer starts when you open the round.
Choose an answer before time runs out
For a name question, type an answer and use the suggestions to choose an entry. For a number question, enter your estimate in the requested unit. Your first valid submission locks the answer. A name that is not recognised can be corrected while the clock continues to run.
Review the answer and keep flying
After submitting, compare your answer with the target and read the revealed value. The result shows your points, altitude change and data source. Use that feedback to build better reference points for future estimates. Complete all seven rounds to see your final altitude and share your result.
How scoring and flight altitude work
Most questions reward proportional closeness: being twice the target is treated like being half the target. An answer within roughly 1% earns a 25-point precision bonus on top of its closeness score. Year questions instead use the distance in years, with the bonus for an exact year. The golden round doubles the points you earn, so a strong estimate there can make a big difference to your flight.
Every point adds 10 metres of altitude. In timed rounds, your plane starts sinking after a three-second grace period, at four metres per second, up to 108 metres per round. A timeout earns no points and applies the full sink. Altitude never drops below zero. Balance accuracy with a timely answer, then use the scoring calculator to explore how different estimates compare.

The daily seven-round challenge
Everyone receives the same daily set of targets. One attempt counts, and the next flight arrives at midnight in New York. Return to the homepage to continue an unfinished flight or view a completed result. Create an account to keep your streak across devices, or start playing as a guest.
Play the daily gamePractice at your own pace
Unlimited practice gives you more chances to learn without waiting for the next daily puzzle. Classic keeps the 30-second timer for a familiar challenge. Discovery removes the timer so you can think through units, compare possible answers and learn from each reveal. Practice is separate from your daily attempt.
Try estimation practiceChallenge another player
Live duels put two players through the same seven rounds on a shared clock. Find an opponent or invite a friend, submit your own estimates and compare the final flight heights. Use practice to build confidence before a duel; recognising the scale of a target is just as useful as recalling a fact.

Start with a familiar reference
Choose a country, planet or element you already know and use it as a reference point. First decide whether the target is in the tens, thousands or millions. Getting the scale right helps you narrow the possibilities before you chase a more precise answer.
Check units and reference years
Read the whole prompt before submitting. Kelvin and degrees Celsius are different scales, and land area is not population. A statistic can also change over time. The source and reference year in the reveal explain which value the game uses for that round.
Learn from each reveal
Review both close guesses and large misses. Ask whether you chose the wrong scale, confused two measurements or simply lacked a useful reference. Discovery practice gives you time to work through those gaps, while Classic helps you make quicker decisions under the daily timer.
Questions, answers and reliable data
The question bank uses a frozen data version so a flight can be scored consistently. Country statistics come from World Bank data, solar-system facts from NASA references and chemical properties from PubChem. Values are checked against the dataset used by the game rather than a live search result. The sources page explains the datasets and their scope, and each reveal identifies the source behind its answer.
