At 94 large 10cm foam blocks across 8 Signature shapes, recommended for 5-8 children, it reaches a scale of construction that the preceding BUILDER sets approach but cannot fully deliver: structures large enough for a child to physically sit on, step across, and use as a piece of play equipment rather than simply a floor arrangement to admire.

The product imagery for the Builder 94 shows this directly. One image shows a boy sitting on or riding a structure built from the blocks - not a small figure built on a table, but a floor structure at a scale where a child's body weight is supported by the construction. That is what 94 large-format 10cm foam blocks, assembled by a group of children, produces. It is the natural endpoint of the BUILDER range: a floor build that becomes a physical environment for play rather than a construction exercise with a result that is observed and then packed away.

The 5-8 child recommendation is also the widest group coverage in the BUILDER range. At 94 blocks for 8 children that is approximately 11-12 blocks per child - every participant has the same access to the construction pool, every sub-structure can be built to completion before combining, and the group build that results from eight children working simultaneously fills a floor space that is genuinely architectural in scale. For kindergartens, special education classrooms running group STEAM activities, occupational therapy programmes with larger group sizes, and institutional play environments where 6-8 children use a construction resource simultaneously, the Builder 94 is the BUILDER set that serves the full group. 

Each block is made from closed-cell EVA foam with a waterproof rotating neodymium magnet capsule. Every face of every block attracts every other face in any orientation. The blocks are EN71-certified, BPA-free, non-toxic, and disinfectable between sessions. The set includes a storage bag and is fully compatible with all other TUKI BIG BUILDER and SMART sets.

Key Features of the TUKI BIG Magnetic Blocks Set - Builder 94

• 94 Large 10cm Magnetic Foam Blocks - Recommended for 5-8 Children - 94 blocks for 5-8 children gives each participant approximately 11-12 blocks, maintaining the self-organising group construction threshold across the widest child group in the BUILDER range
• Builds at a Scale Large Enough for a Child to Sit On - At 94 blocks the combined floor structure produced by a group of children reaches a physical scale where it functions as play equipment - a structure that can support a child's weight and becomes part of the physical play environment, not only a construction exercise
• 8 Signature TUKI Block Shapes - The full 8-shape vocabulary including cubes, beams in multiple variants, L-shapes, and triangles; the same complete shape set as the Builder 43, 56, and 76, with the highest block count in the BUILDER range providing the richest per-shape volume of any set
• 10cm x 10cm x 10cm Large-Format BIG Blocks - Each block is a full 10cm cube, twice the linear dimension of the Regular range and eight times the volume per block; floor-scale, both-hands, whole-body building blocks that develop gross motor planning, bilateral coordination, and proprioceptive body awareness
• Rotating Neodymium Magnet Capsules - Full-Angle Connectivity - Every face of every block attracts every other face in any orientation; no wrong connections, no failed placements; reliable magnetic connectivity at the scale and frequency of 5-8 child group building
• Four Colours - Turquoise, Grey, Yellow and Pink - Ninety-four blocks across four colours provides the highest per-colour block count in the BUILDER range; enough of each colour for dedicated single-colour sub-structures by multiple children simultaneously, with blocks remaining for combined colour group constructions
• Closed-Cell EVA Foam - Waterproof, Disinfectable and Floating - Made from closed-cell EVA foam that does not absorb water; blocks wipe clean or disinfect in seconds between sessions; meets the hygiene standards of kindergartens, therapy rooms, and institutional settings with multiple large groups using shared equipment throughout the day
• EN71-Certified, BPA-Free and Non-Toxic - Certified to EN71-1, EN71-2, and EN71-3 European toy safety standards; BPA-free and non-toxic; independently safety-tested; appropriate for all regulated early years, therapy, and institutional settings
• Compatible with All TUKI BIG BUILDER and SMART Sets - Every block is fully compatible with all other TUKI BIG products; settings that own any BUILDER or SMART set can combine it with the Builder 94 for an even larger shared collection
• Storage Bag Included - The set includes a storage bag designed for institutional large-group use - pack-away, transport, and hygiene management between sessions
• Poland's Toy of the Year 2023 - Made in Poland - Awarded Poland's Toy of the Year 2023; manufactured in Poland to EN71 European standards

What 94 Blocks Actually Builds - and Why That Scale Matters

Every BUILDER set in the TUKI BIG range produces floor constructions. The question across the range is what scale of floor construction is produced, and what a child can do with that construction once it exists.

A Builder 12 or Builder 26 set produces structures that sit on the floor, can be observed from a standing position, and are engaged with by building and then disassembling. A Builder 43 or 56 produces structures that span a meaningful floor area and sustain extended engagement. A Builder 76 produces structures that begin to define a floor zone - large enough that a group of children builds different sections and then occupies them as a shared physical space.

The Builder 94 crosses a threshold that earlier sets cannot reach: structures that are substantial enough for a child to physically interact with as an environment - sitting on a section, stepping across another, using the construction as a physical obstacle course element or play object that responds to body weight. The boy-riding image in this set's product photography is not a marketing exaggeration. It is a documentation of what 94 large-format 10cm foam blocks, assembled by a group, actually produces.

Skills and Developmental Outcomes

• Collaborative Construction and Social Communication at Large-Group Scale - Building with 5-8 children using a shared pool of 94 blocks generates the most sustained and complex collaborative floor construction in the BUILDER range; the group size requires sub-group coordination, distributed leadership, and multi-level social communication across the session
• Gross Motor Planning, Bilateral Coordination and Whole-Body Spatial Awareness - Lifting, carrying, and placing 10cm large-format foam blocks to build structures at sitting-height scale develops the bilateral coordination, motor planning, core strength, and whole-body spatial awareness the largest BUILDER sessions uniquely require
• Proprioceptive Input from Physical Interaction with Completed Structures - When floor structures reach a scale where children can sit on, step across, or push through them, the proprioceptive input from those physical interactions - deep pressure from sitting, balance challenge from uneven surfaces, resistance from pushing - adds a therapeutic dimension that smaller sets cannot produce
• Spatial Reasoning and Large-Scale 3D Engineering - Planning and building a shared structure that physically accommodates 5-8 children as participants and later as users requires the highest level of spatial reasoning, structural planning, and 3D geometric thinking the BUILDER range generates
• Executive Function and Distributed Group Leadership - A 5-8 child build at 94 blocks naturally generates sub-group formation, role differentiation, and distributed decision-making; managing a build at this scale requires executive function, planning, and the leadership communication that educational and therapeutic research identifies as a target outcome of large-group collaborative construction
• Physical Confidence and Embodied Play at Scale - Physically interacting with a child-built structure - sitting on it, stepping across it, playing in and around it - develops the physical confidence, body trust, and willingness to engage with dynamic physical environments that Pikler, RIE, and gross motor development frameworks identify as foundational

Ideal for

• Kindergartens and preschools running large-group construction activities for 5-8 children simultaneously, including special education classrooms with full-group STEAM construction programmes
• Occupational therapy clinics with group programmes of 5-8 children where large-format collaborative floor building is used for social skills, executive function, gross motor, and proprioceptive development
• School sensory rooms, inclusive classrooms, and special education environments where large-format group builds serve both construction and physical play functions
• High-traffic institutional playrooms - hotels, shopping centres, childcare centres, rehabilitation facilities - where a durable, disinfectable large-format construction resource serves multiple large groups daily
• Settings that already own Builder 76 or other BUILDER sets and need to scale to full large-group coverage
• Institutions requiring a permanent, evolving large-scale construction installation that changes and grows with the children who use it
