Where idea turns up in the game

idea is the word under test in two puzzles, spread across two difficulty tiers. It also sits on the board as one of the three wrong tiles in two other puzzles, where the answer is a different word entirely.

The puzzles where idea is the trap

matternoun, Tier 1, Foothills. The answer there is issue, in the sense "some situation or event that is thought about", and idea is on the board beside it.
mindnoun, Tier 3, Ridgeline. The answer there is intellect, in the sense "knowledge and intellectual ability", with idea sitting one tile away.

Play idea

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