12 | 14 | This is a league-based challenge. 15 |
16 | 17 | Wood leagues should be considered as a tutorial which lets players discover the different rules of the game.18 | In Bronze league, all rules will be unlocked and the real challenge will begin. 19 | 20 |
25 | 26 | The Goal 27 |
28 |30 | You pilot a submarine. You know that an enemy is present nearby because you are listening to its radio frequency communication. 31 | You don't know exactly where it is but you can hear all of its orders.
32 | You and your opponent start with
38 | 39 | Rules 40 |
41 |Environment
43 |-
44 |
- The map is a square tiling:
15 cells wide and15 cells high. The NW corner is(0,0) ; the SW corner is(0,14).
45 | - Each map cell is either open water or an island. Islands are obstacles. Submarines cannot move to or through islands. Nor can torpedoes or mines. 46 |
- Submarines move on the open water cells of the map. Each player controls one submarine; both submarines move independently. They can share the same water cell without colliding. 47 |
- The map is split in
9 sectors. Each sector encompasses a5×5 block of25 cells. You can find the sectors' numbering in the viewer; the top left sector is number1 and the bottom right sector is number9 .

Game start
51 |52 | At the beginning of the game, you'll receive a full 15×15 map that indicates the position of the islands. 53 | You will then decide and reply where you want your submarine's starting position to be. 54 |
55 |56 |
Turns
57 |This is a turn-based game: each player plays a turn one after the other. The whole game lasts
During your turn, thanks to your radio frequency analysis, you will receive an indication of what your opponent has done. 59 | For example, you can receive that it moved to the north. It's up to you to use this valuable information to detect where the opponent actually is. 60 |
61 |62 | During your turn, you must perform at least one action. 63 |
64 |65 |
Actions
66 |
67 | Actions are your turn's output. They are provided sequentially, on a single line. You can chain several of them using a pipe symbol
But you can use each type of action only once per turn. For example you can
72 |
Move
73 |A move action has two effects:
74 |-
75 |
- It moves your submarine by
1 cell in a chosen direction (north, east, south, west).
76 | - It charges a special power of your choice, i.e. increases its energy level by
1 .
77 |
When you move, you must respect the following rules:
79 |- You cannot move through islands. 80 |
- You cannot move to a cell you have visited before. 81 |
83 |
Powers
84 |For each move action you take, you have to decide what special power to charge. The special powers are performed by different devices, who require a different amount of energy to be ready.
85 |The energy levels are separate per device, not shared. The amounts of energy needed to activate a device are also distinct per device.
86 | A device's energy is fully consumed when that device's power is used. The energy level cannot grow above that device's requirement for one use of the power.
87 |
88 | In this league you only have access to the torpedo. 89 |
90 |Surface
91 | The surface action will reset your path of visited cells, so that you can freely move to a cell that you have previously visited. 92 | But surfacing has major impacts: your opponent will know in which sector you are surfacing, and you will lose94 |
Torpedo
95 | The torpedo action requires an energy level of99 |
100 | 101 |
Explosions
102 |When a torpedo or a mine explodes on a water cell, any submarine present on that cell and its 8 neighbors suffers a loss of hit points. The damage is
103 |
104 | 105 |
Explosions damage your opponent's submarine and yours indiscriminately. They have no effect on anything else (mines, islands).

Orders' visibility
110 | The following table shows how different actions will be shown to your opponent: 111 || Your action | Shown to opponent | Comment |
|---|---|---|
| The opponent will not see which power is charged. | 117 |||
| The opponent will see which sector (in this case: |
122 | ||
| The opponent will see the same order you issued. | 127 |
-
145 |
- Don't respond in time.
146 |
- Output an ill-formed order.
147 |
- Reach
0 hit points or lower (while your opponent still has more than you).
