purple group · The short answer
PHRASES HIDING GREEK LETTERS
Each puzzle word passes the same exact test. The four mappings show how the answer works.
FREEZE TAG hides ZETA across the boundary: freeZE TAgg, using the final two letters of FREEZE and first two of TAG.
HOME GAME contains OMEGA continuously across the space: hOME GAme supplies the complete five-letter sequence.
MODEL TANK hides DELTA across its boundary: moDEL TAnk contributes three letters before the space and two after it.
ORAL PHASE contains ALPHA across the space: orAL PHAse joins the final two letters of ORAL to the first three of PHASE.
Why this group was difficult
- The phrases do not share a useful surface subject
A playground game, a sporting event, a miniature vehicle and a developmental expression point in unrelated semantic directions. - Every hidden name crosses a space
The relevant sequence is split between two words, so scanning each word separately will miss the pattern. - DELTA appears openly elsewhere on the board
Seeing DELTA as its own tile can discourage looking for the same letter sequence concealed within MODEL TANK. - The hidden sequences have different boundary splits
The names divide two-plus-two, three-plus-two or two-plus-three across the spaces, so one fixed extraction rule does not suffice.
How to spot this pattern next time
On a board with several multiword entries, temporarily remove each space and scan the resulting continuous string. Pay special attention to sequences that cross the former boundary.
Do not require hidden words to split at the same point. The stable rule here is continuous spelling across a phrase, while the number of letters taken from each side varies.
Use surface meaning only as a first pass. When phrases have sharply different subjects, their spelling, sound or internal structure is often the stronger level to test.
Four useful facts behind the group
- FREEZE TAG contains ZETA across its word boundary.
- HOME GAME contains OMEGA across its word boundary.
- MODEL TANK contains DELTA across its word boundary.
- ORAL PHASE contains ALPHA across its word boundary.
Questions players ask
The details people search after seeing the group
Which Greek letter is hidden in FREEZE TAG?
ZETA appears continuously across the space, using ZE from FREEZE and TA from TAG.
Which Greek letter is hidden in HOME GAME?
OMEGA runs across the boundary as OME from HOME followed by GA from GAME.
Which Greek letter is hidden in MODEL TANK?
DELTA is formed by DEL at the end of MODEL and TA at the beginning of TANK.
Which Greek letter is hidden in ORAL PHASE?
ALPHA is formed by AL at the end of ORAL and PHA at the beginning of PHASE.
How can I spot hidden-word phrase groups again?
Ignore spaces temporarily, scan across word boundaries and test whether every candidate conceals the same kind of named item.
