In this guide
1 · Step or jump?
Coral is at A; B is adjacent and empty. No piece lies between them. Is A → B legal, and what kind of move is it?
Position as text
Reduced teaching position; other pieces are omitted. Coral I9. A = I9; B = I8. One step: A → B reaches the adjacent empty point.
Answer and explanation
Yes: one step. It needs no supporting piece. You cannot add a jump afterwards in the same turn.
2 · How many turns does the chain take?
The coral piece travels A → B → C → D. All shown supports are occupied and every landing is empty. How many turns are needed, and which pieces disappear?
Position as text
Reduced teaching position; other pieces are omitted. Coral E9; Green F9; Blue H8; Coral I6. A = E9; B = G9; C = I7; D = I5. Three jumps in one move: A → B → C → D. All jumped pieces remain.
Show hint
Distinguish an individual jump from a complete turn.
Answer and explanation
One turn containing three jumps. No jumped piece disappears. You may stop at B or C; reaching D is optional.
3 · May the first jump go backwards?
Coral is heading up but first jumps A → B downwards. Is A → B → C → D legal?
Position as text
Reduced teaching position; other pieces are omitted. Coral I9; Green I10; Blue J10; Green K8. A = I9; B = I11; C = K9; D = K7. Useful detour: A → B initially goes backwards; the chain continues through C to D farther up.
Answer and explanation
Yes. Backward jumps are allowed and each segment has a support and empty landing. D ends two rows above A. The direct A → D route has no support.
4 · Leave the target again?
The coral piece starts its turn at A inside its target camp. X is immediately outside. May it move A → X?
Position as text
Reduced teaching position; other pieces are omitted. Coral J4. A = J4; X = J5. Target lock: coral at A cannot leave its target camp for X. The dashed connection is forbidden.
Answer and explanation
No. In our edition, a piece starting in the target stays within it during that turn. It may still move to empty points within the camp.
5 · The final step
Nine coral pieces occupy the target; only B is empty. The tenth is at A. Does A → B win?
Position as text
Reduced teaching position; other pieces are omitted. Coral K4; Coral L4; Coral M4; Coral K3; Coral L3; Coral M3; Coral L2; Coral M2; Coral M1; Coral J5. A = J5; B = J4. Finishing: nine coral pieces are in the target camp. A → B brings in the tenth.
Answer and explanation
Yes. The checked step fills the tenth target point with coral and satisfies the win condition. Earlier route lengths and the opponent’s partial arrivals do not affect that condition.
