Essential Tips for Beginners

1. Use the Checkerboard Pattern

The single most important tip: adopt a checkerboard search pattern. Imagine the board as a checkerboard and only fire at squares of one color. Since the smallest ship (destroyer) is 2 squares long, it must occupy at least one square of each color. By systematically hitting all squares of one color, you guarantee hitting every ship at least once while only searching 50 squares instead of 100.

How to do it: Start at A1, skip A2, fire at A3, skip A4, fire at A5, and so on. On row B, start with B2 (skipping B1), fire at B4, B6, B8, B10. Continue this alternating pattern across the entire grid.

2. Never Abandon a Hit

When you score a hit, immediately focus on sinking that ship before resuming your search pattern. This is called "Target Mode" and it's crucial for efficiency. Check the four adjacent squares (up, down, left, right) systematically until you determine the ship's direction, then continue firing in that direction until it's sunk.

Common mistake: Hitting a ship, noting the location, and then continuing your original search pattern. This wastes your hard-earned information and gives the opponent more time to sink your ships.

3. Start in High-Probability Squares

Not all checkerboard squares are equal. Center squares like D4, D7, G4, and G7 can accommodate more potential ship placements than edge or corner squares. After your first few games, prioritize these high-value squares early in your checkerboard pattern.

4. Track What's Still Hunting You

Pay attention to which enemy ships you've sunk. If you've destroyed the carrier, battleship, and cruiser, you know only the submarine and destroyer remain. This tells you to search for 3-square and 2-square ships, allowing you to skip large open areas that couldn't hide these smaller vessels.

5. Spread Your Ships Apart

When placing ships, distribute them across different quadrants of the board. Clustering ships together means one successful enemy search area can locate multiple vessels. Spreading forces opponents to search the entire grid, buying you more time.

Intermediate Tactics

6. Think About Ship Orientation

After your first hit, consider which directions have enough space for different ship sizes. If you hit at H2 and there are only 3 squares to the right before the edge, you know that hit can't be the left end of the carrier (which needs 5 squares). Use this logic to eliminate possibilities and target smarter.

7. The "Second Hit" Decision

After scoring one hit, you have four possible directions to check. Choose wisely: prioritize directions toward the center of the board where ships are more likely to extend. Also avoid directions where you've already confirmed misses nearby - ships can't jump over empty water.

8. Count Your Shots

Track roughly how many shots you're taking per ship sunk. Good players average 8-12 shots per ship sunk. If you're consistently over 15 shots per sink, you're either not using a systematic pattern or abandoning hits too early. This feedback helps identify what to improve.

9. Avoid Adjacent Misses

If you fire at E5 and miss, don't immediately fire at E4, E6, D5, or F5. These squares are directly adjacent to confirmed empty water, making them lower probability unless you're in Target Mode pursuing a known ship. Stick to your checkerboard pattern instead.

10. Use the Edge Squeeze

When you hit a ship near an edge, you have valuable information - the ship can only extend in three directions instead of four. If your hit is in a corner, the ship can only extend in two directions. Use edge positions to your advantage by eliminating impossible directions immediately.

Ship Placement Tips

11. Don't Always Use Edges

It's tempting to place ships along edges for "protection," but many opponents search edges early knowing this tendency. Mix up your placements - sometimes use edges, sometimes use center positions. Unpredictability is your friend.

12. Separate Your Destroyer

Your 2-square destroyer is statistically the last ship found in most games. Place it far from your other ships, ideally in an area opponents would search last. Some players hide it in corners, others in the center. Experiment to find what works against your typical opponents.

13. Mix Orientations

Don't place all ships horizontally or all vertically. Mix orientations to make yourself less predictable. If an opponent notices you favor horizontal placements, they'll optimize their search pattern accordingly. Variety keeps them guessing.

14. One Square Gaps

Try to leave at least one empty square between ships when possible. This prevents opponent search patterns from discovering multiple ships in one area. If ships touch, a concentrated enemy search gains information about multiple vessels simultaneously.

15. Change Your Style

Don't use the same placement strategy every game. Vary your approach - sometimes cluster ships, sometimes spread them. Sometimes use edges, sometimes avoid them. This prevents you from developing exploitable patterns and keeps your gameplay fresh.

Advanced Quick Tips

16. Probability After Hits

Once you've hit a ship but haven't sunk it, the four adjacent squares become extremely high probability. In fact, one of those four squares has a 100% chance of containing the ship. Don't let systematic patterns override this certainty - always clear adjacent squares after a hit.

17. The Last Ship Advantage

When only one enemy ship remains, you know exactly what size you're looking for. Use this! If it's the destroyer, focus on small 2-square gaps in your search pattern. If it's the carrier, only check areas with 5 consecutive open squares. This late-game knowledge significantly speeds up your final hunt.

18. Eliminate Impossible Zones

As the game progresses, you'll create zones where ships simply cannot fit due to surrounding misses. If you've created a pocket with only 3 consecutive open squares and the remaining ships are all 4+ squares, skip that area entirely. Focus probability on viable zones.

19. The Double Hit Ambiguity

If you hit two adjacent squares but continuing in that direction misses, you've likely found two different ships placed next to each other. Switch to checking perpendicular directions (if you hit horizontally adjacent squares, now check vertically adjacent). This reveals which hit belongs to which ship.

20. Adjust for Difficulty Level

Lower AI difficulties (Ensign, Lieutenant) fire less optimally, giving you more time to find their ships. Against these opponents, you can use slightly riskier ship placements and focus purely on offensive optimization. Against higher difficulties (Captain, Admiral), defensive placement becomes more critical - these AI punish mistakes quickly.

Mental Game Tips

21. Stay Disciplined

The hardest part of Battleship isn't knowing what to do - it's actually doing it consistently. When you hit a long string of misses, it's tempting to abandon your checkerboard pattern and start firing randomly. Resist this urge. Mathematics doesn't care about short-term variance. Your systematic approach will win over many games.

22. Learn From Losses

After losing a game, take a moment to review what happened. Did the opponent find your ships unusually fast? Maybe your placement was too predictable. Did you take too many shots to win? Perhaps you need to tighten your search pattern. Each loss contains lessons that make you stronger.

23. Don't Rush

While there's no time limit at Sinkships, faster play feels more exciting. However, taking an extra few seconds to think through your shot - considering ship sizes, probability, and previous patterns - often pays off. Speed comes naturally with practice; focus on accuracy first.

24. Visualize Remaining Ships

Develop the habit of mentally visualizing where remaining ships could physically fit on the board. After each miss, consciously note which potential ship placements you've just eliminated. This mental tracking helps you recognize high-probability squares intuitively.

25. Practice Progressive Difficulty

Don't jump straight to Admiral difficulty. Start with Ensign, master the basics, then gradually increase difficulty as you win consistently. Each level teaches new lessons about strategic thinking. Rushing to the hardest difficulty before you're ready just creates frustration.

Common Mistakes to Avoid

• Random firing: Always use a systematic search pattern, never just click random squares
• Forgetting ship sizes: Track which ships remain so you know what you're hunting
• Predictable placement: Vary your ship positions between games
• Incomplete targeting: Always sink a ship completely before resuming your search
• Ignoring probability: Understand that center squares are statistically more valuable early game
• Edge obsession: Don't automatically assume ships hide along edges
• Pattern abandonment: Stick with your checkerboard even during losing streaks
• Adjacent searching: Don't fire next to confirmed misses unless pursuing a known hit

Quick Reference Checklist

Before each shot, mentally run through this checklist:

1. Am I in Target Mode? If I have an unsunk hit, clear adjacent squares first
2. What ships remain? Know what sizes I'm searching for
3. Following my pattern? Stick to checkerboard unless in Target Mode
4. Is this square possible? Could a remaining ship actually fit here?
5. High probability? Am I targeting statistically favorable squares?
