Daily Challenge
Two Rings, One Cell
Can a small pink and a medium mint ring share one cell? Compare two placements, then open an optional hint and explanation.
Difficulty: Normal
Ring practice: 3 of 3. This round stands on its own. For a tray-placement warmup, try Three Rings, Three Spaces first.
Do the rings need separate cells?
Your tray has a small pink ring and a medium mint ring. Place both using cells A, B, and C below. Each cell holds at most one ring of each size: small, medium, and large. Existing rings stay fixed. There are no matches, clears, scores, or color requirements in this exercise.
Cell A
- Small
- Empty
- Medium
- Empty
- Large
- Purple
Cell B
- Small
- Mint
- Medium
- Empty
- Large
- Pink
Cell C
- Small
- Gold
- Medium
- Gold
- Large
- Empty
Solid rings show occupied sizes; dashed rings show empty sizes. The labels below each cell give the same information in words. This is a read-and-solve example, not a playable board.
Compare these choices for the medium mint ring:
- Put it in A, then find a home for small pink.
- Put it in B, then find a home for small pink.
Does one choice prevent you from finishing, or can both work? Try naming the size position each new ring would use.
Show a small hint
Small pink needs an empty small position. Only A has one. Would a medium ring in A use that same position, or a different one?
Show the placements and explanation
Small pink must go in A. B already has a small mint ring, and C already has a small gold ring. Their colors do not change the occupied-size rule.
Medium mint can go in A or B. Both medium positions are empty. C already has a medium gold ring, so it is not compatible.
There are exactly two completed assignments:
- Small pink in A, medium mint in A.
- Small pink in A, medium mint in B.
In the first assignment, A holds small pink, medium mint, and its original large purple ring. Those are three different sizes. Putting medium mint there first does not take the small position away. Either tray order works for either assignment.
Splitting the new rings across A and B also works. In this placement-only exercise, neither finish earns a higher score or a better result. The goal is simply to place both rings legally.
Take the idea into a quick game
Try Daily Ring Puzzle to place five rings with the same one-ring-per-size rule. Its board is separate from this exercise, and it finishes when the tray is placed; no line clear is required.
Revisit Ring Puzzle Basics for the size check, or start the three-round practice again. The exercises are fixed, so a bookmark returns to the same question without a timer or streak.
For the separate color rings game, visit Ringzzle or play Ringzzle online. Check that game’s own rules before applying a color-line strategy; the examples here are placement-only.
