How they work
Play Therapy
Core mechanism: Play as the child's natural language enables expression, mastery, and processing of experiences that words cannot reach
Ontology: Children's distress is expressed through play, not verbal insight; play is the developmental medium for processing
Sandtray Therapy
Core mechanism: Creating symbolic scenes in sand with miniature figures allows unconscious material to be expressed, witnessed, and integrated without requiring verbal articulation
Ontology: The psyche speaks in images and symbols before it speaks in words; the sand world externalizes inner experience into a tangible, rearrangeable form

What each assumes — and misses
Play Therapy
Philosophical roots: Piaget (play as cognitive development); Vygotsky (play as zone of proximal development); Winnicott (transitional space, playing); Axline (child-centered approach via Rogers); Klein (play as child's free association)
Blind spots: Evidence base is modest; age-limited; transition to verbal therapy can be poorly managed
Therapeutic voice: [Following the child's lead in play] The bear is going somewhere safe? Tell me about that safe place.
Sandtray Therapy
Philosophical roots: Jung (archetypes, active imagination); Lowenfeld (World Technique); Kalff (free and protected space); Winnicott (transitional space)
Blind spots: Limited empirical evidence; Jungian interpretation may be imposed; requires extensive miniature collection; therapist training in symbolic interpretation varies widely
Therapeutic voice: Build whatever wants to be built in the sand. There's no right or wrong way. I'll be here watching.
Choosing between them
Play Therapy (Humanistic) and Sandtray Therapy (Expressive) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
