Name & Purpose Down to One is a group logic puzzle inspired by the classic peg solitaire game. Players stand on spots arranged in a triangle. The group works together to eliminate spots one by one through checkers-style jumps β until only one player remains on the board. It builds strategic thinking, collective decision-making, and patience.
a.k.a. Pyramid Puzzle, Leap and Land
Age Band / Group Size / Time / Space Ages 8β16 | 9β10 participants per puzzle (run two simultaneous puzzles for larger groups) | 20β35 minutes | Flat floor or outdoor surface with room for a triangle 5 spots wide at the base
Materials
- 10 poly spots, carpet squares, or paper plates
- Arrange in a triangle: 5 spots on bottom row, 4 on next, 3, 2, 1 at the tip
Quick-Run Card
- Lay 10 spots in a triangle formation.
- Players stand on spots. Leave one spot empty β the group chooses which one.
- A player “jumps” by stepping over an adjacent player into an empty spot. The jumped player steps off the triangle.
- Only diagonal or straight-line jumps are valid (checkers rules).
- Players can only move during their own jump or when being jumped.
- Group deliberates together: “Who jumps next?”
- Goal: reduce to one player remaining on the triangle.
- If stuck, reset. Try removing a different starting spot.
Setup & Boundaries
- Spots should be close enough to step over but not so close that players are physically crowded.
- Establish a “thinking zone” β a place just outside the triangle where stepped-off players can watch and advise.
- Do not position spots near walls, steps, or trip hazards.
- For younger groups, use a smaller triangle (6 spots, 3-2-1) as a starter.
How to Play The group starts with all but one spot occupied. The empty spot is their starting gap. On the group’s collective “go,” one player jumps. The jumped player steps off to the thinking zone. Now there is a new empty spot. The group discusses the next move. Continue until no more jumps are possible. Count remaining players β fewer is better. Reset and attempt again with a different opening gap or jump sequence.
I-OPt Roles Three roles operate at all times:
- Active jumper β the player currently being asked to jump. Executes the move after group agreement.
- Thinkers-on-triangle β all other players on the triangle, contributing to the group’s next-move decision.
- Thinking zone advisers β players who have stepped off. They observe and offer suggestions, but cannot make decisions for the active group. All participants cycle through all three roles naturally as the game progresses.
Inclusion Supports
- Participants who cannot step over a spot (mobility limitations) can “jump” by touching their foot to the destination spot and being assisted to move, or a facilitator can physically represent their movement with a marker.
- For a seated version, replace standing players with cups or cones and play as a tabletop group puzzle β one participant moves pieces on behalf of the group.
- Participants in the thinking zone can use drawings or a printed triangle diagram to map out possible moves.
- Allow extra thinking time between jumps β do not rush the group’s deliberation.
Stewardship Participants who step off collect their spot when the puzzle ends. 30-second reflection: “What’s one decision the group made together that you personally would not have made alone β and how did it turn out?”
Consent Pre-brief: “This game doesn’t involve physical contact with other players. You’ll step over a spot on the ground β not over another person. When you step off the triangle, you join the thinking zone and keep contributing.” Mid-game check-in: After the first failed attempt, ask: “How’s the group’s energy? Do we reset right away or talk through what we saw first?” Opt-out / re-entry: Any participant may move to the thinking zone at any time. They rejoin by taking an available spot at the start of the next reset.
Risks & Mitigation
| Risk | Likelihood | Mitigation |
|---|---|---|
| Participant trips stepping over spots | Low | Ensure adequate distance between spots; no rushing moves |
| Group frustration when puzzle seems unsolvable | Medium | Facilitator validates: “This is genuinely hard. Keep going β the solution exists.” |
| One participant dominates all decisions | Medium | Facilitator asks: “Let’s hear from the thinking zone β what do you see?” |
| Participants who step off feel excluded | Low | Frame thinking zone as a power position β advisers have the best view |
Warm-Up Suggestions
- “One-move chess”: pairs face each other, take turns moving one spot toward a goal β quick intro to sequential thinking.
- “What’s my strategy?” β facilitator lays 6 spots in a mini triangle and has the group call out one move sequence aloud before playing.
Debrief What? “Did your group solve it? If not, how close did you get?” So what? “How did the group make decisions? Did everyone’s ideas get heard?” Now what? “Think of a group challenge at school or at home where you had to plan multiple steps ahead. What strategy did you use? Would today’s game change how you approach it?”
Cleanup & Reset Collect all spots. Stack or bag. Check triangle area for spots left behind.
