Solve a guessing round: a worked example
A useful guess changes what you know about the answer. This lesson follows a small candidate set through two feedback rows, explains why each candidate survives or disappears, and turns the result into a repeatable practice routine. You can test your conclusion before opening the solution.
A, B, C and D are invented teaching candidates, not real League of Legends records. Their years, ranges and regions are deliberately simplified so that the exercise tests deduction rather than champion memory. Real rounds compare the primary attributes stored by LoL Game.
1. Separate facts from assumptions
Begin with the table below. All four candidates use the same resource, so a resource match cannot separate them in this example. The release year, attack range and region can. Do not add facts that the table does not contain: a ranged candidate is not automatically a mage, and region β does not imply a particular role. In a real round, check each feedback column on its own before combining the results. A familiar champion name should not overrule a conflicting clue.
| A–D | Release year | Attack range | Region |
|---|---|---|---|
| A | 2015 | Melee | α |
| B | 2020 | Ranged | β |
| C | 2017 | Ranged | α |
| D | 2018 | Ranged | β |
2. Read the first feedback row
Your first guess is A. The target's release year is later than 2015, its range does not match melee, and its region does not match α. Write the allowed set instead of immediately choosing a favourite: the year must be greater than 2015, the range must be ranged in this two-range example, and the region must be β. A fails the year condition. C is newer and ranged, but its region is still α, so it also fails. B and D satisfy all three conditions and remain possible.
3. Keep the confirmed attributes
Next you guess B. The range and region now match, while the year clue says earlier than 2020. Keep the range and region as confirmed facts; the year clue adds an upper bound rather than cancelling the first row. Together, the rows require a year after 2015 and before 2020, ranged attacks and region β. Notice why C cannot return to the shortlist just because its 2017 year fits. A candidate must satisfy the complete set of clues, not only the latest one.

4. Explain the answer before submitting
D is the only remaining candidate: 2018 lies strictly between 2015 and 2020, its attacks are ranged and its region is β. B matches the categorical clues but its 2020 year is excluded by the second row. A and C have region α. In a real round, do the same check before spending another attempt: name the clue that justifies your candidate, and identify any column for which you still lack evidence. If several candidates remain, the clues have narrowed the group without proving a unique answer.
5. Spot three avoidable mistakes
The first mistake is reading an earlier-year clue as '2020 or earlier'; a mismatch means 2020 itself is excluded. The second is treating any green cell as proof of the champion instead of proof of one attribute. The third is discarding the older feedback after a new guess. Keep a short note of confirmed facts and strict year bounds. If the visible feedback seems inconsistent with a champion, compare the site's reference attributes and report the page and language through Contact; do not silently change the rule to fit your assumption.
6. Turn one round into a learning exercise
If the correct answer D is submitted on the third guess in Medium mode, the score is 28 × (8 − 3 + 1) ÷ 8 = 21. That is a scoring example, not a claim that three guesses are always optimal. After your next real round, record the first candidate you could have ruled out sooner and the exact clue that excludes it. Repeat on the same difficulty once, then compare your reasoning. Use the portrait and ability quizzes separately to practise recognition; their five-question scores do not enter the main leaderboard.
7. Compare a different first guess
Starting with B would shorten this particular exercise. Against target D, B immediately gives the earlier-year clue and matching range and region. A and C fail the region condition; B fails the strict year bound, leaving D for the second guess. In Medium that would earn 24 instead of 21 points. This is a property of this small table, not proof that B or any real champion is always the best opener. Compare how a candidate separates the remaining possibilities rather than memorising one opening name.
