How to play
Connect the islands with straight bridges (1 or 2 between two islands), without crossings: each island carries as many bridges as its number, and everything must be connected.
Example
The two 3s are joined by a double bridge (═), then each goes down to its 1 with a single bridge (│). Every island has its number of bridges, and everything is connected.
A full Easy grid
A real Easy grid (5 × 5), as you play it, and its solution. Same rule as the example above, only bigger.
Tips to get better
- An 8 in the middle, or a 4 in a corner, has two bridges in every possible direction.
- An island with a single neighbour sends all its bridges to it.
- Mind the network rule: two islands of 1 can't be linked only to each other, they would be cut off from the rest.
What this game trains
- Logical reasoning: deduce the solution from the rules, without guessing.
- Planning and strategy: think several moves ahead and organise your actions.
