Build a Boat for Treasure Best Blocks (2026) — Top 10 Ranked

Quick answer: The Gold Block (9 HP) is the best standard block in Build a Boat for Treasure in 2026. It has the highest hitpoints of any regular building material and can only be earned by completing runs—not bought from the shop.

Build a Boat for Treasure by Chillz Studios has been running since November 2016 and has racked up over 4.9 billion visits. With roughly 21,000 concurrent players and 196+ blocks & items in the game, choosing the right materials for your boat matters more than most people realize.

Every block has a hitpoints (HP) value that determines how many obstacle hits it can absorb before it breaks apart. Heavier blocks sink faster, lighter blocks float better, and the wrong mix of materials will leave your boat in pieces before you reach the treasure chest. We've ranked the 10 best blocks below based on HP, weight, availability, and overall usefulness.

10. Wood Block

The Wood Block sits at the bottom of the ranking, but it still earns a spot on this list. Why? Because it's the most accessible block in the entire game. Every player starts with Wood Blocks, and you'll never run out of them.

At just 1 HP, a single obstacle hit will destroy a Wood Block instantly. That makes it terrible as armor. But it's perfect as interior filler, decorative elements, or the structural skeleton of your boat where obstacles won't directly hit.

For newer players still learning the game, Wood is the training-wheels material. Build a full wood boat, learn the obstacle patterns, then upgrade piece by piece. Check our Build a Boat for Treasure free Robux guide for tips on progressing faster.

9. Sand Block

The Sand Block doubles the HP of Wood while staying cheap and light. At 2 HP, it can survive one obstacle hit before taking critical damage—a small but meaningful upgrade over Wood's instant destruction.

Sand is one of those transitional materials that new players should grab early. It won't carry you through the hardest stages, but it gives your boat enough extra durability to reach further than a pure Wood build ever could.

The main drawback is that 2 HP still isn't much. By the time you're regularly completing runs, Sand Blocks feel fragile. Use them as a stepping stone on your way to better materials.

8. Rusted Block

The Rusted Block hits the sweet spot for budget-conscious builders. At 3 HP, it can handle two obstacle impacts before breaking, and it's still cheap enough to use in bulk without burning through your gold reserves.

Think of Rusted Blocks as your first "real" building material. They're noticeably tougher than Sand or Wood, and the weight increase is modest enough that your boat won't sink immediately in calm water.

Rusted Blocks work best as secondary armor—the layer behind your front-facing hull blocks. When the outer Obsidian or Gold eventually breaks, Rusted Blocks buy you a few more seconds to reach the next checkpoint.

7. Plastic Block

The Plastic Block isn't on this list for its durability. It's here because it weighs almost nothing—just 0.001 balloons, making it the lightest block in Build a Boat for Treasure by a wide margin.

Weight management is a hidden skill in this game that separates average builders from great ones. Every heavy block adds to your boat's float rating, and once you cross 60, your vessel starts riding dangerously low in the water. Plastic lets you add volume and structure without moving that number.

The best application for Plastic Blocks is in flying machines, jump ramps, and any build where you need mass without weight. Pair a Plastic body with an Obsidian or Gold hull, and you get a boat that's both tough and agile through the rapids.

6. Brick Block

The Brick Block is the first block on this list that genuinely feels durable. At 4 HP, it can absorb three hits before breaking, and it's readily available in the shop for a reasonable price.

Brick is the workhorse material for mid-level players. It's strong enough to survive most early-stage obstacles and cheap enough to build a full boat out of. You won't win any speed records, but your build will hold together.

Where Brick falls short is its weight-to-HP ratio. It's noticeably heavier than Plastic or even Sand for only a modest HP boost. In the rapids sections, that extra weight can drag your boat under if you haven't balanced it with lighter materials elsewhere.

5. Concrete Block

Concrete Block is where things start getting serious. At 5 HP, it sits right in the middle of the durability scale and offers a solid balance of toughness and cost for players who want reliable armor.

Five hitpoints means four obstacle impacts before destruction. That's enough to survive most of the early and mid-game stages without constant repairs. For players who aren't yet farming Gold Blocks regularly, Concrete is arguably the best all-around material you can buy.

The catch is weight. Concrete is heavier than everything below it on this list, so you'll want to keep your float rating in check. A smart approach is using Concrete for the bow and waterline of your boat while filling the interior with lighter Plastic or Wood blocks.

4. Steel Block

The Steel Block delivers 6 HP—enough to survive five direct obstacle hits. That kind of durability makes it a strong choice for the front of your boat where it takes the most punishment.

Steel is the first block in this ranking that falls into the "metal" category, and metal blocks share a common trade-off: highest defense but heavy weight. A boat built entirely from Steel will sink fast in deeper water sections and struggle to clear jumps.

The best Steel builds use it strategically. Place Steel Blocks on your bow and along the sides that face obstacles. Fill everything else with Plastic or Wood to offset the weight. This layered approach gives you strong armor where it counts without turning your boat into an anchor.

3. Titanium Block

Titanium Block offers 7 HP with a better strength-to-weight ratio than Steel. It's one of the sturdiest materials in Build a Boat for Treasure and doesn't drag your boat down as much as you'd expect for a high-HP block.

Seven hitpoints means six obstacle impacts before the block breaks. That's enough to carry your bow through nearly all of the game's obstacle courses in a single run, assuming you're not taking constant hits on the same spot.

Titanium costs more than Steel in the shop, so it's not the most gold-efficient option for full builds. The smart play is using Titanium on the 10–15 blocks that take the most direct hits—your bow, your keel, and the leading edges of your hull. Let cheaper materials handle the rest.

2. Obsidian Block

The Obsidian Block is the most underrated material in the game, and frankly, it might be the best practical choice for most players. At 8 HP, it's just one hitpoint below Gold—but it weighs only 0.5 balloons and you can buy 50 of them for 425 gold in the shop.

That combination is absurd. You get near-top-tier durability at a fraction of the weight of metals like Steel or Titanium. A full Obsidian boat barely affects your float rating, handles smoothly through rapids, clears jumps with ease, and still tanks seven obstacle hits per block.

The only reason Obsidian isn't ranked #1 is that Gold technically has one more HP. But in terms of pure value—considering cost, availability, weight, and durability—Obsidian is the block that most players should be building with. If you can only buy one material from the shop, make it Obsidian.

1. Gold Block

The Gold Block sits at the top of the ranking with 9 HP—the highest hitpoints of any standard building material in Build a Boat for Treasure. It can absorb eight obstacle impacts before it breaks, giving your boat the maximum possible durability per block.

There's a catch, though. Gold Blocks can't be purchased from the shop. The only way to get them is by completing a full run and opening the treasure chest at the end. This means Gold is a reward for skilled players who can already survive the obstacle course—a nice bit of design that makes every successful run feel meaningful.

The ideal strategy is to start with Obsidian builds (since you can buy those), farm Gold Blocks from successful runs, and gradually replace your Obsidian hull with Gold. Over time, your boat becomes nearly indestructible at the front while staying light enough to handle well through the course.

Gold's weight is heavier than Obsidian but lighter than Steel, putting it in a comfortable middle ground. For the absolute strongest boat, use Gold on the bow and front-facing surfaces, Obsidian on the sides and deck, and Plastic for interior filler. That layered approach gives you maximum HP where it matters most.

Honorable Mentions

A few blocks didn't make the top 10 but deserve a shout-out for specific situations.

Huge Wheel — At 40 HP, the Huge Wheel has the most hitpoints of any item in the game. It's technically not a standard building material, but creative players have used Wheels as makeshift armor on the front of their boats. If you don't mind the look, it works.

Shield Generator — This ability block creates a temporary shield around your boat, absorbing hits without damaging your structure at all. It's situational, but devastating when timed correctly before a cluster of obstacles.

Neon Blocks & Star Blocks — Available through codes, these blocks add visual flair to your build. They're not the strongest options, but they look great and they're free. Grab them from our codes page before they expire.

Chest Blocks — The rarest blocks in the game drop from the Legendary Chest at a 1 in 1,000 chance. They're more of a collector's item than a practical building material, but owning one is a serious flex in any lobby.
