Where acid turns up in the game

acid is the word under test in one puzzle, at Tier 2, Treeline. It also sits on the board as one of the three wrong tiles in three other puzzles, where the answer is a different word entirely.

The puzzles where acid is the trap

effectiveadjective, Tier 2, Treeline. The answer there is efficient, in the sense "able to accomplish a purpose", and acid is on the board beside it.
elementaryadjective, Tier 2, Treeline. The answer there is primary, in the sense "of or being the essential or basic part", with acid sitting one tile away.
radicaladjective, Tier 3, Ridgeline. The answer there is ultra, in the sense "far beyond the norm", so acid is there to be ruled out.

Play acid

The bank on this page is the bank the game plays from, so acid reaches you as a board rather than a definition: the sentence first, four tiles, and the meaning after you choose.

Every word is an answer somewhere and a trap somewhere else

acid is an answer in 1 puzzle and a wrong tile in 3. That is how the bank is built, and it is why guessing by vibe stops working around tier three.
