The Doctor’s regenerations and actors

About this quiz

What you’ll test in this Doctor Who quiz

From Hartnell to the latest incarnation, this quiz focuses on linking each regeneration to the correct actor and placing them in the right sequence.

Every question is multiple-choice with 4 options and no timer, so you can think through tricky era overlaps and casting details at your own pace.

Difficulty, length, and how scoring feels fair

Choose how many questions you want to play and select a difficulty setting before you start; the full set contains 115 questions with Mixed difficulty overall.

The balance comes from blending straightforward “who played this Doctor?” items with deeper cuts (special cases, transition points, and commonly confused eras) so newer viewers aren’t locked out and veterans still get stretched.

Common pitfalls (and quick ways to avoid them)

Mixing up adjacent eras where costumes and tones feel similar (especially around major showrunner shifts)
Confusing the War Doctor and other non-numbered incarnations with the numbered lineup
Assuming broadcast order always matches in-universe chronology when recalling regenerations
Overthinking when two actors share similar timeframes in expanded material discussions
Forgetting that some questions may focus on actor identification rather than episode trivia

Tips to improve fast

If you miss one, pause and mentally anchor that Doctor to a signature companion, season vibe, or debut story—then replay with a shorter question count to reinforce the weak spots before tackling a longer run again.
