wahn, rising from mid to high. Identical in sound to 玩 — same lip-rounding, same open vowel, same climb.
wán
The climb never shifts. In its most common role as a resultative complement — chī wán, kàn wán, zuò wán — it attaches to a preceding verb and keeps its rising tone, though it is often spoken quickly. That rise is what distinguishes the completed action from a plain verb.

我吃完了。 gives four distinct pitch states in three and a bit syllables: wǒ dips, chī holds high, wán climbs, le fades. Wǒ keeps its full dip because chī is a first tone. And le, being toneless, sits at whatever height wán reached — which is high, so the sentence ends up rather than down despite being a completed statement.
The rise gets swallowed because the syllable functions as a suffix and feels unimportant, which leaves a level wan that reads as a first tone. Keep the climb. The vowel is the other issue: English speakers produce "won" with a back rounded quality carried over from the glide, when the mouth should open and unround as soon as the w is done.
